Aston Institute of Membrane Excellence’s Dr Matt Derry was joined by Dr Alan Goddard and France-based research partner Dr Mona Semsarilar They discussed the BIOMEM project, which received £3m from the European Innovation Council (EIC) Pathfinder programme BIOMEM will develop a bioinspired membrane to selectively extract compounds from water (like finding a favourite chocolate in a box) In the latest Aston Institute for Membrane Excellence (AIME) podcast, three researchers discuss the international BIOmimetic selective extraction MEMbranes (BIOMEM) project and how it will feed into AIME’s work.
BIOMEM will develop a bioinspired membrane technology to selectively extract compounds from water, using 50-75% less energy than current state-of-the-art nanofiltration technologies. The membranes will work at low pressures and at low concentration of the target molecule.
Podcast host Dr Matt Derry was joined by fellow AIME researcher Dr Alan Goddard and Dr Mona Semsarilar from the French National Centre for Scientific Research (Centre national de la recherche scientifique (CNRS)).
The BIOMEM project, which involves collaborators from across Europe, is being led by Dr Torsten Bak from Danish company Aquaporin, with Dr Goddard the research lead at Aston University.
Dr Goddard explained:
“You might want to work on a biotechnology process where you've made a high value chemical that you want to extract from a complex mix, and at the moment you might have to concentrate your solution up, and you might have to do six or seven filtration steps. We want a filter that does it in a single step using a biological transporter.
“And if you can do that in a single step in a platform technology, you'll make all these brilliant biotech processes more commercialisable, reduce your reliance on petrochemicals, and to maybe oversell what we can do, save the planet.”
Dr Derry likened it to a quick way to find your favourite chocolate in a box at Christmas. Rather than scrabbling through, taking out one type at a time until you find your favourite, the process can immediately separate it out with minimal effort.
Aquaporin has developed a membrane that can selectively transport only water molecules to quickly purify water, which is already in use across the world, and even out of this world, for space missions. Dr Bak and the team will bring their membrane expertise to the project.
The team at CNRS, led by polymer scientist Dr Semsarilar, is working on a number of projects for BIOMEM, including developing a type of crystalline material called trianglamine, which they can modify through chemical processes to be hydrophobic or hydrophilic to make things like water channels or adsorption sites, which can be embedded in polymer network for purification processes.
Other researchers at AIME, including Dr Derry and Professor Paul Topham, will work on the ‘glue’ to stick the biological elements of the membranes to the non-biological polymer matrix.
BIOMEM will also benefit from the input of partners across Europe including dsm-firmenich, University of Copenhagen and Tampere University.
The podcast was recorded just after the project kick-off meeting with all the project partners, which was held at Aston University in May 2024.

Professor Roslyn Bill discusses her research into brain cell membranes with Dr Matt Derry Serious brain injuries and dementia are affected by the flow of water through a protein called aquaporin-4 in brain cell membranes Aquaporins are responsible for clearing the build-up of waste products in brain cells in a process Professor Bill likens to a ‘dishwasher for your brain’. Professor Roslyn Bill, co-founder of Aston Institute for Membrane Excellence (AIME), joins Dr Matt Derry to discuss her research into brain cell membranes in the latest Aston Originals podcast. Water moves in and out of brain cells through tiny protein channels in the cell membrane called aquaporins. One in particular, aquaporin-4, is the focus of Professor Bill’s research.
In 2020, she was lead author on a paper published in prestigious journal Cell on how the channels open and close and how this can be controlled. Uncontrolled water entry into brain cells can occur after head trauma, causing swelling which leads to severe brain injuries of the type suffered by racing driver Michael Schumacher after a skiing accident. Finding drugs to control this water movement could lead to treatments to prevent brain swelling in the first place.
This research into brain swelling and the contribution of aquaporins led Professor Bill to research into Alzheimer’s, a common form of dementia, which is also related to the action of aquaporins. Alzheimer’s is caused by a build-up of waste products in brain cells. In a process Professor Bill likened to a ‘dishwasher for your brain’, aquaporins are responsible for clearing this waste as we sleep.
Professor Bill was selected for an Advanced Grant by the European Research Council (ERC) in 2023, which is being funded by UK Research and Innovation (UKRI). The funded project will further investigate the process, and whether it might be possible to develop a drug to boost the ‘brain dishwasher’, which could be taken to slow or even prevent cognitive decline due to ageing.
Bringing together this biological research with the polymer research of AIME, chemists like Dr Derry will help in the drug development and could also lead to totally different applications.
Professor Bill said in the podcast to Dr Derry:
“We can take the knowledge that we have of how these proteins work in cells and try and apply them to interesting applications in biotechnology. And this is where the sort of work that you (Dr Derry) do comes in, where you can develop plastic membranes, polymer membranes, and then take learning from the biology and try and make really, really good ways of purifying water, for example.”

Image shows how tiny water channels control how water enters and exits cells through their membranes The Aston Institute for Membrane Excellence (AIME) will be set up with a £10m grant from Research England AIME will be led by Professor Roslyn Bill from Biosciences and Professor Paul Topham from Chemical Engineering and Applied Chemistry The globally unique institute will use biomimetic polymer membranes for applications such as water purification and drug development Aston University will establish the Aston Institute for Membrane Excellence (AIME), a globally unique, cross-disciplinary institute to develop novel biomimetic membranes, after receiving a major grant of £10m from Research England.
AIME will be led by Professor Roslyn Bill, from the School of Biosciences, with co-lead Professor Paul Topham from the department of Chemical Engineering and Applied Chemistry (CEAC).
Membranes, both biological and synthetic, are hugely important in many sectors. For example, the world’s top ten selling human medicines all target proteins in biological membranes, while synthetic polymer membranes are used in the US$100bn/year water purification industry. The team behind AIME believes that the full potential of membranes will only be realised by an interdisciplinary group spanning biology, physics and chemistry that can investigate membranes holistically.
Professor Bill, a European Research Council (ERC) Advanced grantee leads Aston Membrane Proteins and Lipids (AMPL) research centre of excellence that studies the structure and function of membrane proteins and associated lipids. Professor Topham leads Aston Polymer Research Group (APRG), which investigates the nanoscale behaviour of block copolymers (a type of polymer with a structure made of more than one type of polymer molecule) and polymer technologies for membranes. AMPL and APRG have already begun collaborative research and AIME will bring together the complementary expertise of both research clusters into one institute.
AIME will initially comprise the eight researchers from AMPL and APRG. Alongside the co-leads Professor Bill and Professor Topham, will be Dr Alan Goddard, Professor Andrew Devitt, Professor Corinne Spickett, Dr Alice Rothnie, Dr Matt Derry and Dr Alfred Fernandez. It plans to recruit three further academics, six tenure-track research fellows, three postdoctoral research assistants (PDRAs), six PhD students, a research technician and a business development manager. Importantly, AIME will work with many existing Aston University colleagues to build a comprehensive research community focused on all aspects of membrane science.
The new AIME team will focus on the development of bioinspired, highly selective polymer structures for applications in water purification and waste remediation, nanoparticles loaded with therapeutic molecules to treat disorders ranging from chronic wounds to neurological injuries, and the purification of individual membrane proteins with polymers to study them as drug targets.
The vision is for AIME to become a ‘one-stop shop’ for interdisciplinary, translational membrane research through its facilities access and expertise, ideally located in the heart of the country.
Professor Bill said:
“The creation of AIME is ground-breaking. Together with Aston’s investment, E3 funding will deliver a step-change in scale and the rate at which we can grow capacity. We will address intractable scientific challenges in health, disease, and biotechnology, combining our world-class expertise in polymer chemistry and membrane biology to study membranes holistically. The excellence of our science, alongside recent growth in collaborative successes means we have a unique opportunity to deliver AIME’s ambitious and inclusive vision.”
Professor Topham said:
“We are really excited by this fantastic opportunity to work more closely with our expert colleagues in Biosciences to create advanced technology to address real world problems. From our side, we are interested in molecular engineering, where we control the molecular structure of new materials to manipulate their properties to do the things that we want! Moreover, we are passionate about a fully sustainable future for our planet, and this investment will enable us to develop technological solutions in a sustainable or ‘green’ way.”
Professor Aleks Subic, Vice-Chancellor and Chief Executive of Aston University, says:
“Our new Aston Institute for Membrane Excellence (AIME) will be a regional, national, and international research leader in membrane science, driving game-changing research and innovation that will produce a pipeline of high-quality research outcomes leading to socioeconomic impact, develop future global research leaders, create advanced tech spinout companies and high value-added jobs for Birmingham and the West Midlands region. Its establishment aligns perfectly with our 2030 strategy that positions Aston University as a leading university of science, technology and enterprise.”
Steven Heales, Policy Manager (Innovation) at the West Midlands Combined Authority, said:
“WMCA is delighted to see Research England back the Aston Institute for Membrane Excellence. This will enable Aston University’s excellent academics and research community to work closely with businesses to make advances in membrane technology and applications.
“In 2023 the West Midlands Combined Authority agreed a Deeper Devolution Trailblazer Deal with Government, which included a new strategic innovation partnership with Government. Projects like AIME are exactly the kind of impact we expect this new partnership to generate, so watch this space.”
Lisa Smith, chief executive of Midlands Mindforge, the patient capital investment company formed by eight Midlands research-intensive universities including Aston University, said:
“This grant is an important vote of confidence in the Midlands scientific R&D ecosystem. AIME will play an important role in the future research of pioneering breakthroughs in membrane science and enable the world-leading research team at Aston University to develop solutions to real world problems. We look forward to closely working with the Institute and nurturing best-in-field research being undertaken at Aston out of the lab and into the wider society so it can make a positive impact”.
Rob Valentine, regional director of Bruntwood SciTech, the UK’s leading developer of city-wide innovation ecosystems and specialist environments and a strategic partner in Birmingham Innovation Quarter, said:
"As a proud supporter of the Aston Institute for Membrane Excellence (AIME), I am thrilled at the launch of this groundbreaking initiative. AIME exemplifies Aston University's commitment to advancing cutting-edge interdisciplinary research and further raises the profile of the region’s exemplary research capabilities and sector specialisms.
AIME's vision of becoming a 'one-stop shop' for translational membrane research, strategically located at the heart of the country, aligns perfectly with our strategy at Bruntwood SciTech. We are committed to working with partners, including Aston University, to develop a globally significant innovation district at the heart of the UK where the brightest minds and most inspiring spaces will foster tomorrow’s innovation.”
Membrane research at Aston University has also recently received two other grants. In November 2023, Professor Bill received £196,648 from the Biotechnology and Biological Sciences Research Council’s Pioneer Awards Scheme to understand how tiny membrane water channels in brain cells keep brains healthy. In December 2023, a team led by AIME team-member Dr Derry received £165,999 from the Engineering and Physical Sciences Research Council to develop biomimetic membranes for water purification.

Exploring Microphase Separation in Semi-Fluorinated Diblock Copolymers: A Combined Experimental and Modeling InvestigationClick to copy article link
ACS Polymers Au
2025
We report the combined experimental and theoretical study of the bulk self-assembly behavior of polystyrene-block-poly(2,3,4,5,6-pentafluorostyrene) diblock copolymers. These block copolymers were designed to create highly antagonistic blocks (with a high Flory–Huggins interaction parameter, χ) with minimum disruption to the molecular construct (i.e., only replacing five hydrogen atoms with five fluorine atoms). A large library of diblock copolymers (41 samples) was synthesized by reversible addition–fragmentation chain transfer (RAFT) polymerization to map out a major portion of the phase space. All block copolymers exhibited narrow molecular weight distributions with dispersity (D) values between 1.07 and 1.32, and subsequent thermal annealing revealed phase separation into well-defined nanoscale morphologies depending on their molecular composition, as determined from small-angle X-ray scattering and transmission electron microscopy analyses, with an experimental phase diagram being constructed. The χ value at 25 °C for this block copolymer was estimated to be 0.2 using strong segregation theory, based on trends in phase-separated domain spacing and interfacial width.
Block copolymer synthesis in ionic liquid via polymerisation-induced self-assembly: a convenient route to gel electrolytes†
Chemical Science
2024
We report for the first time a reversible addition–fragmentation chain transfer polymerisation-induced self-assembly (RAFT-PISA) formulation in ionic liquid (IL) that yields worm gels. A series of poly(2-hydroxyethyl methacrylate)-b-poly(benzyl methacrylate) (PHEMA-b-PBzMA) block copolymer nanoparticles were synthesised via RAFT dispersion polymerisation of benzyl methacrylate in the hydrophilic IL 1-ethyl-3-methyl imidazolium dicyanamide, [EMIM][DCA]. This RAFT-PISA formulation can be controlled to afford spherical, worm-like and vesicular nano-objects, with free-standing gels being obtained over a broad range of PBzMA core-forming degrees of polymerisation (DPs). High monomer conversions (≥96%) were obtained within 2 hours for all PISA syntheses as determined by 1H NMR spectroscopy, and good control over molar mass was confirmed by gel permeation chromatography (GPC).
Heterotelechelic homopolymers mimicking high χ – ultralow N block copolymers with sub-2 nm domain size
Chemical Science
2022
Three fluorinated, hydrophobic initiators have been utilised for the synthesis of low molecular mass fluoro-poly(acrylic acid) heterotelechelic homopolymers to mimic high chi (χ)–low N diblock copolymers with ultrafine domains of sub-2 nm length scale. Polymers were obtained by a simple photoinduced copper(II)-mediated reversible-deactivation radical polymerisation (Cu-RDRP) affording low molecular mass (
Structure Control Using Bioderived Solvents in Electrochemical Metal-Organic Framework Synthesis
Applied Sciences
2023
Electrochemical synthesis of metal-organic frameworks (MOFs) has proven to possess many environmental advantages over traditional synthesis methods such as reduced energy use and shorter reaction times. However, the use of toxic, fossil fuel derived solvents such as N,N-dimethylformamide (DMF) presents a challenge to the environmental credentials of this method that has yet to be dealt with. Here, we investigate bioderived solvents, CyreneTM and γ-valerolactone (GVL), as an alternative for the synthesis of a range of MOFs via the anodic deposition method. The obtained MOF materials are characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM) to confirm their identities and morphologies and for comparison with MOFs synthesized using the traditional DMF-based solvent systems. When using CyreneTM and GVL solvents, crystalline MOF materials were obtained of comparable quality to those afforded using DMF. However, in several cases, using CyreneTM or GVL led to the formation of less stable, higher porosity MOF structures than those obtained using DMF, indicating that the larger bio solvent molecules may also play a templating role during the synthesis. This study successfully demonstrates the first-time electrochemical synthesis of MOFs has been performed using bio solvents and has highlighted that the use of bio solvents can provide a route to obtaining lower density, higher porosity MOF phases than those obtained using traditional solvents.
The contents of biological cells are retained within compartments formed of phospholipid membranes. The movement of material within and between cells is often mediated by the fusion of phospholipid membranes, which allows mixing of contents or excretion of material into the surrounding environment. Biological membrane fusion is a highly regulated process that is catalyzed by proteins and often triggered by cellular signaling. In contrast, the controlled fusion of polymer-based membranes is largely unexplored, despite the potential application of this process in nanomedicine, smart materials, and reagent trafficking. Here, we demonstrate triggered polymersome fusion. Out-of-equilibrium polymersomes were formed by ring-opening metathesis polymerization-induced self-assembly and persist until a specific chemical signal (pH change) triggers their fusion. Characterization of polymersomes was performed by a variety of techniques, including dynamic light scattering, dry-state/cryogenic-transmission electron microscopy, and small-angle X-ray scattering (SAXS). The fusion process was followed by time-resolved SAXS analysis. Developing elementary methods of communication between polymersomes, such as fusion, will prove essential for emulating life-like behaviors in synthetic nanotechnology.
Block Copolymer Nanoparticles Prepared via Polymerization-Induced Self-Assembly Provide Excellent Boundary Lubrication Performance for Next-Generation Ultralow-Viscosity Automotive Engine Oils
ACS Applied Materials & Interfaces
2019
Core cross-linked poly(stearyl methacrylate)–poly(benzyl methacrylate)–poly(ethylene glycol dimethacrylate) [S31–B200–E20] triblock copolymer nanoparticles were synthesized directly in an industrial mineral oil via polymerization-induced self-assembly (PISA). Gel permeation chromatography analysis of the S31–B200 diblock copolymer precursor chains indicated a well-controlled reversible addition–fragmentation chain transfer dispersion polymerization, while transmission electron microscopy, dynamic light-scattering (DLS), and small-angle X-ray scattering studies indicated the formation of well-defined spheres. Moreover, DLS studies performed in THF, which is a common solvent for the S and B blocks, confirmed successful covalent stabilization because well-defined solvent-swollen spheres were obtained under such conditions. Tribology experiments using a mini-traction machine (MTM) indicated that 0.50% w/w dispersions of S31–B200–E20 spheres dramatically reduce the friction coefficient of base oil within the boundary lubrication regime. Given their efficient and straightforward PISA synthesis at high solids, such nanoparticles offer new opportunities for the formulation of next-generation ultralow-viscosity automotive engine oils.
