Aston University researcher develops new optical technique that could revolutionise medical diagnostics

New light technique could revolutionise non-invasive medical diagnostics Orbital Angular Momentum could be harnessed to improve imaging and data transmission through biological tissues Could eventually have potential to make procedures such as surgery or biopsies unnecessary. An Aston University researcher has developed a new technique using light which could revolutionise non-invasive medical diagnostics and optical communication. The research showcases how a type of light called the Orbital Angular Momentum (OAM) can be harnessed to improve imaging and data transmission through skin and other biological tissues. A team led by Professor Igor Meglinski found that OAM light has unmatched sensitivity and accuracy that could result in making procedures such as surgery or biopsies unnecessary. In addition it could enable doctors to track the progression of diseases and plan appropriate treatment options. OAM is defined as a type of structured light beams, which are light fields which have a tailored spatial structure. Often referred to as vortex beams, they have previously been applied to a number of developments in different applications including astronomy, microscopy, imaging, metrology, sensing, and optical communications. Professor Meglinski in collaboration with researchers from the University of Oulu, Finland conducted the research which is detailed in the paper “Phase preservation of orbital angular momentum of light in multiple scattering environment” which is published in the Nature journal Light Science & Application. The paper has since been named as one of the year’s most exciting pieces of research by international optics and photonics membership organisation, Optica. The study reveals that OAM retains its phase characteristics even when passing through highly scattering media, unlike regular light signals. This means it can detect extremely small changes with an accuracy of up to 0.000001 on the refractive index, far surpassing the capabilities of many current diagnostic technologies. Professor Meglinski who is based at Aston Institute of Photonic Technologies said: “By showing that OAM light can travel through turbid or cloudy and scattering media, the study opens up new possibilities for advanced biomedical applications. “For example, this technology could lead to more accurate and non-invasive ways to monitor blood glucose levels, providing an easier and less painful method for people with diabetes.” The research team conducted a series of controlled experiments, transmitting OAM beams through media with varying levels of turbidity and refractive indices. They used advanced detection techniques, including interferometry and digital holography, to capture and analyse the light's behaviour. They found that the consistency between experimental results and theoretical models highlighted the ability of the OAM-based approach. The researchers believe that their study’s findings pave the way for a range of transformative applications. By adjusting the initial phase of OAM light, they believe that revolutionary advancements in fields such as secure optical communication systems and advanced biomedical imaging will be possible in the future. Professor Meglinski added: "The potential for precise, non-invasive transcutaneous glucose monitoring represents a significant leap forward in medical diagnostics. “My team’s methodological framework and experimental validations provide a comprehensive understanding of how OAM light interacts with complex scattering environments, reinforcing its potential as a versatile technology for future optical sensing and imaging challenges.” ENDS https://www.nature.com/articles/s41377-024-01562-7 Light: Science & Applications volume 13, Article number: 214 (2024) August 2024 https://doi.org/10.1038/s41377-024-01562-7 Authors: Igor Meglinski, Ivan Lopushenko, Anton Sdobnov & Alexander Bykov About Aston University For over a century, Aston University’s enduring purpose has been to make our world a better place through education, research and innovation, by enabling our students to succeed in work and life, and by supporting our communities to thrive economically, socially and culturally.

Aston University develops novel bone cancer therapy which has 99% success rate

Bioactive glasses, doped with gallium developed to create a potential treatment for bone cancer Lab tests have a 99 percent success rate of killing cancerous cells Method could also regenerate diseased bones. Bioactive glasses, a filling material which can bond to tissue and improve the strength of bones and teeth, has been combined with gallium to create a potential treatment for bone cancer. Tests in labs have found that bioactive glasses doped with the metal have a 99 percent success rate of eliminating cancerous cells and can even regenerate diseased bones. The research was conducted by a team of Aston University scientists led by Professor Richard Martin who is based in its College of Engineering and Physical Sciences. In laboratory tests 99% of osteosarcoma (bone cancer) cells were killed off without destroying non-cancerous normal human bone cells. The researchers also incubated the bioactive glasses in a simulated body fluid and after seven days they detected the early stages of bone formation. Gallium is highly toxic, and the researchers found that the ‘greedy’ cancer cells soak it up and self-kill, which prevented the healthy cells from being affected. Their research paper Multifunctional Gallium doped bioactive glasses: a targeted delivery for antineoplastic agents and tissue repair against osteosarcoma has been published in the journal Biomedical Materials. Osteosarcoma is the mostly commonly occurring primary bone cancer and despite the use of chemotherapy and surgery to remove tumours survival rates have not improved much since the 1970s. Survival rates are dramatically reduced for patients who have a recurrence and primary bone cancer patients are more susceptible to bone fractures. Despite extensive research on different types of bioactive glass or ceramics for bone tissue engineering, there is limited research on targeted and controlled release of anti-cancer agents to treat bone cancers. Professor Martin said: “There is an urgent need for improved treatment options and our experiments show significant potential for use in bone cancer applications as part of a multimodal treatment. “We believe that our findings could lead to a treatment that is more effective and localised, reducing side effects, and can even regenerate diseased bones. “When we observed the glasses, we could see the formation of a layer of amorphous calcium phosphate/ hydroxy apatite layer on the surface of the bioactive glass particulates, which indicates bone growth.” The glasses were created in the Aston University labs by rapidly cooling very high temperature molten liquids (1450o C) to form glass. The glasses were then ground and sieved into tiny particles which can then be used for treatment. In previous research the team achieved a 50 percent success rate but although impressive this was not enough to be a potential treatment. The team are now hoping to attract more research funding to conduct trials using gallium. Dr Lucas Souza, research laboratory manager for the Dubrowsky Regenerative Medicine Laboratory at the Royal Orthopaedic Hospital, Birmingham worked on the research with Professor Martin. He added: “The safety and effectiveness of these biomaterials will need to be tested further, but the initial results are really promising. “Treatments for a bone cancer diagnosis remain very limited and there’s still much we don’t understand. Research like this is vital to support in the development of new drugs and new methodologies for treatment options.” Notes to Editors Multifunctional Gallium doped bioactive glasses: a targeted delivery for antineoplastic agents and tissue repair against osteosarcoma Shirin B.

National Institutes of Health award $1.827 million for research on collective cell migration featured image

National Institutes of Health award $1.827 million for research on collective cell migration

Priscilla Hwang, Ph.D., assistant professor in the Department of Biomedical Engineering at Virginia Commonwealth University, has received a National Institutes of Health grant for $1.827 million over five years. The award from the National Institute of General Medical Sciences will support Hwang’s innovative research project “Dissecting mechanisms of collective migration” and provide mentorship for student researchers from the high school to graduate level. Collective migration, where groups of cells move together in a coordinated manner, is critical for the successful development of tissues and plays a vital role in wound healing, metastasis, and other biological processes. Dysregulation in collective migration is often linked to developmental abnormalities and disease progression. Despite its importance, the mechanics and mechanisms driving collective migration remain poorly understood. The project is organized around three primary goals: Investigate the effect of biomechanical cues to activate leader cells and directional collective migration: Understand how biomechanical signals activate leader cells to guide the migration of cell groups. Elucidate which and how leader cell mechanics are responsible for leader cell development: Identify the specific mechanical properties and behaviors that enable leader cells to emerge and lead the collective migration process. Examine the role of cell junctional forces in collective migration: Explore how the forces at cell contacts contribute to the overall migration and coordination among cells. Hwang will leverage her expertise in 3D microphysiological systems to study collective migration in dynamic, physiologically relevant environments. Her work aims to uncover the mechanisms by which leader cells sense and respond to mechanical forces in their environment, driving the collective migration of cells. “Our understanding of collective migration, especially the mechanics and mechanisms driving this phenomenon, is very limited,” Hwang said. “Our proposal will significantly accelerate our progress toward a comprehensive understanding of collective migration and lay the foundation for advancing treatment for developmental abnormalities or diseases.” The NIH grant will also expand student research and mentoring opportunities. “This Maximizing Investigators Research Award (MIRA) only goes to the most highly talented and promising investigators, and Dr. Hwang is most deserving,” said Rebecca L. Heise, Ph.D., Inez A. Caudill, Jr. Distinguished Professor and chair of the Department of Biomedical Engineering . “The award will provide support for undergraduate and predoctoral research opportunities in this important area of fundamental research that has an impact on neonatal development, cancer, and fibrotic disease.” To ensure diverse perspectives are considered throughout the project, Hwang said students from diverse populations will be recruited, including underrepresented minorities, women, and first-generation college students. “Further, we will continue to share our passion for science with the community through developing hands-on outreach activities based on our research findings,” she added.

Saving Lives, One Device at a Time: Clinical Engineering featured image

Saving Lives, One Device at a Time: Clinical Engineering

Behind every health care provider, or perhaps already in the palms of their hands, is a piece of equipment necessary to their patient’s health and survival. Modern medical treatment relies on complex equipment to keep patients alive and healthy during procedures and recovery. Take live-saving equipment such as telemetry monitors, MRI machines and ventilators as just a few examples. But what happens when all that equipment needs repair? Enter ChristianaCare’s clinical engineering technicians. This team of 35 employees — one of the largest clinical engineering teams in the nation — is responsible for overseeing the care, testing and repair of the roughly 50,000 pieces of medical equipment in use throughout the ChristianaCare system. The Clinical Engineering team is overseen by Director Blake Collins, MBA, CBET, CHTM, nationally recognized for excellence in the profession. He brings two decades of experience as a clinical engineer in the United States Navy, seven of which were served with the U.S. Marine Corps, to his role. His team has won numerous trade industry awards for its success as a “solutions provider” for the health system. "Think of health care as a triangle,” said Collins. “You have the patient, the provider and the equipment. You can’t have successful health care delivery without those three elements.” Begun in the 1970s as the hospital system’s “TV repair shop,” he joked, the Clinical Engineering department evolved dramatically after subsequent national developments in electrical safety testing and oversight for the care and functionality of medical equipment. ‘Everyone truly cares’ Today, the Clinical Engineering department maintains close to 50,000 pieces of medical equipment throughout the ChristianaCare system, including its three hospitals and all its imaging centers. “From thermometers to linear accelerators, MRIs, CTs — we manage all of it,” Collins said. Last year, the team completed 25,000 work orders, or roughly 2,100 per month. “We get to help people in so many different ways,” said John Learish, Clinical Engineering manager. Samantha Daws, Clinical Engineering supervisor, echoed the sentiment. “The Clinical Engineering Department within ChristianaCare is the most talented group of technicians I have ever had the privilege to work with,” she said. “Everyone truly cares about keeping the equipment working to ensure all caregivers have what is needed to provide quality health care to our community.” Saving lives, one device at a time What’s so important about what Clinical Engineering offers to ChristianaCare? In short: Anyone could need medical care at any time, and if medical equipment were out of commission or wrongly calibrated, lives would be at stake. Collins recalls a pivotal moment during his tenure in the Navy, when he needed an emergency appendectomy while stationed on board an aircraft carrier. “I was the only biomedical technician on the ship,” he said. “And the doctor doing the procedure asked me, jokingly, ‘Hey Collins, is this equipment going to work?’ “He was kidding, but it’s true that we never know when we or a loved one is going to end up under the equipment that we work on as engineers.” This experience gained new significance for Collins after successful open-heart surgery at ChristianaCare in 2022 — followed by his mother, who had the same procedure, also successfully, in 2023. “I had not one inkling or shadow of a doubt that the equipment was going to work fine,” he said. “You never know who will end up needing care. So we take it very, very seriously.” Icon in the field For his outstanding service as Director of Clinical Engineering at ChristianaCare, Collins was presented with the 2024 John D. Hughes Iconoclast Award from the Association for the Advancement of Medical Instrumentation (AAMI), a career-marking honor in health care technology management. The award recognizes innovation and leadership in the field; for Collins, it shows how well the Clinical Engineering team works together to deliver safe medical equipment across the ChristianaCare system. “Blake has been a relentless advocate for ChristianaCare,” read his nomination. “He has implemented numerous initiatives and processes to improve his department … and work smarter through the use of technology and automation.” The next time you see a ChristianaCare provider pick up an instrument or turn on a machine, think about the Clinical Engineering team — and rest assured that your equipment is ready to go.

Aston University to help Saudi Arabia turn waste into energy

Energy will help power new cities in the desert Aston University is in talks about converting waste products into vital energy Its Energy and Bioproducts Institute is experienced in the waste-to-energy sector through global collaborations. Aston University researchers are to help turn waste into energy to power new cities in the desert. The University has started talks with experts from Saudi Arabia, including those who are building two sustainable cities in the desert, called NEOM and The Line. They are to collaborate with Aston University and its Energy and Bioproducts Research Institute (EBRI) to explore how they can convert waste products into vital energy. The scientists and engineers are to apply their expertise to help Saudi Arabia create technology to convert discarded matter into a source of energy and other innovations such as using date palm waste to transform desert sand to allow it to retain water and grow crops. Aston University also hosted a two-day conference in March to discuss how to develop and apply the technology. The event is a key element of the UK-KSA Waste2Energy project supported by the Foreign, Commonwealth and Development Office under the Gulf Strategy Fund (GSF) programme and is led by senior lecturer in mechanical, biomedical and design engineering Dr Muhammad Imran. More than 70 delegates attended the conference, including representatives from King Abdulaziz City for Science and Technology (KACST), King AbdulAziz University, The National Research and Development Center for Sustainable Agriculture and the Saudi Investment Recycling Company (SIRC).

Inspired by Palm Trees' Resilience, Florida Tech Researcher Seeks to Strengthen Made Materials

Inspired by the tiny, circular vessels in the trunks of palm trees that allow the iconic plants to bend but not snap in strong winds, an assistant professor of aerospace engineering is researching how to recreate Mother Nature’s handiwork in additive manufacturing. Mirmilad Mirsayar received a three-year, $200,627 research grant from the National Science Foundation’s highly competitive Mechanics of Materials and Structures program under the Division of Civil, Mechanical and Manufacturing Innovation to study the mechanics and physics of crack propagation in functionally graded cellular structures made by additive manufacturing. That’s the process of creating an object by building it one layer at a time. Mirsayar is the sole principal investigator of the project, “Understanding Mixed-Mode Fracture Mechanics in Additively Manufacturable Functionally Graded Microcellular Solids.” His research is inspired by cellular patterns seen in palm trees and butterfly wings. For example, unlike oak trees and some others, the palm tree’s center contains those vessels, distributed non-uniformly throughout the trunk, that help it survive in Florida’s windy environment. Other biological systems, such as bone, honeycombs and marine sponges, also serve as inspirations from nature. “I’m enjoying this research because I’m learning from nature and I’m applying fundamentals of physics and mathematics to solve a very important engineering problem while training the next generation of engineers and researchers,” Mirsayar said. Materials with cellular structures, such as aircraft wings and artificial bones, are widely used in industries such as aerospace and biomedical. As additive manufacturing has advanced, materials with cellular structures and increasingly complex geometrical patterns can be precisely manufactured. Mirsayar is looking at ways to optimize these strong and light cellular structures made by additive manufacturing to achieve the highest resistance against failure under complex operational loading conditions, such as bending tension, compression and torsion. What could this mean for additive manufacturing? How could stronger materials change what or how we build? Contact Florida Tech Media Communications Director Adam Lowenstein at adam@fit.edu to schedule an interview with Dr. Mirsayar.
