Biosynthesis of Silver Nanoparticles using Upland Cress: Purification, Characterisation, and Antimicrobial Activity

Micro & Nano Letters

David Johnson, Yale Wang, Samuel Stealey, Anne Alexander, Matey Kaltchev, Junhong Chen, and Wujie Zhang

2020 Silver nanoparticles have traditionally been synthesised using physical and chemical methods, often requiring expensive equipment and reagents that pose risks to the environment. This work provides a green method for the biosynthesis of silver nanoparticles using leaf extracts from upland cress: Barbarea verna. Natural reducing agents within the leaf extracts of upland cress reduce silver ions from silver nitrates, resulting in the formation of silver nanoparticles. The silver nanoparticles were purified using centrifugation and extraction using Triton X-114. The resulting nanoparticles were characterised using UV–Vis spectroscopy, dynamic light scattering, atomic force microscopy, and scanning electron microscopy. Silver nanoparticles were shown to have a diameter of 30–40 nm with a characteristic UV–Vis absorption peak at 420 nm. Antimicrobial properties of the synthesised silver nanoparticles were also confirmed using S. epidermis and E. coli bacteria.

Calcium-Oligochitosan-Pectin Microcarrier for Colonic Drug Delivery

Pharmaceutical Development and Technology

Samuel Stealey, Xiaoru Guo, Rebecca Majewski, Alexander Dyble, Kendra Lehman, Michael Wedemeyer, Douglas A. Steeber, Matey G. Kaltchev, Junhong Chen, and Wujie Zhang

2020 Pectin-based hydrogel microcarriers have shown promise for drug delivery to the colonic region. Microcarriers must remain stable throughout the upper gastrointestinal tract for effective colonic delivery, an issue that traditional pectin-based microcarriers have faced. The positively-charged natural biopolymer oligochitosan and divalent cation Ca2+ were used to dually cross-link pectin-based hydrogel microcarriers to improve carrier stability through simulated gastric and intestinal environments. Microcarriers were characterized with Scanning Electron Microscope and Fourier-Transform Infrared analysis. An optical microscope was used to observe the change of microcarrier size and morphology over time in the simulated gastrointestinal environments. Fluorescently-labeled Dextran was used as a model drug for this system. Calcium-Oligochitosan-Pectin microcarriers exhibited relatively small drug release in the upper gastrointestinal regions and were responsive to the high pH and enzymatic activity of simulated col

Design of A Novel Oxygen Therapeutic Using Polymeric Hydrogel Microcapsules Mimicking Red Blood Cells

Pharmaceutics

Amanda Cherwin, Shelby Namen, Justyna Rapacz, Grace Kusik, Alexa Anderson, Yale Wang, Matey Kaltchev, Rebecca Schroeder, Kellen O'Connell, Sydney Stephens, Junhong Chen, and Wujie Zhang

2019 The goal of this research was to develop a novel oxygen therapeutic made from a pectin-based hydrogel microcapsule carrier mimicking red blood cells. The study focused on three main criteria for developing the oxygen therapeutic to mimic red blood cells: size (5–10 μm), morphology (biconcave shape), and functionality (encapsulation of oxygen carriers; e.g., hemoglobin (Hb)). The hydrogel carriers were generated via the electrospraying of the pectin-based solution into an oligochitosan crosslinking solution using an electrospinning setup. The pectin-based solution was investigated first to develop the simplest possible formulation for electrospray. Then, Design-Expert® software was used to optimize the production process of the hydrogel microcapsules. The optimal parameters were obtained through the analysis of a total of 17 trials and the microcapsule with the desired morphology and size was successfully prepared under the optimized condition. Fourier transform infrared spectroscopy (FTIR) was used to ana

2019 Bioprinting offers an alternative approach for tissue engineering and exhibits the great potential to play a key role in personalized medicine. One of the major advantages of bioprinting is its capability of achieving the homogeneous distribution of cells within large tissue scaffolds. Microspheres have been used for controlled release of bioactive molecules in tissue engineering. Recently studies show that microspheres, especially positively charged, could promote the vascularized tissue formation. This study aims to develop a bioprinted scaffold containing microspheres. The double emulsion system, water in oil in water (W/O/W), was used to produce the microspheres considering its advantage for controlled release of small molecules. Design Expert® Software was used to optimize the microsphere production process and chitosan coating was performed to provide the positively charged surface of the microspheres. Fourier-transform infrared spectroscopy (FTIR) and confocal microscopic analysis confirmed the suc

Electrospinning pectin-based nanofibers: a parametric and cross-linker study

Applied Nanoscience

McCune, D., Guo, X., Shi, T., Stealey, S., Antrobus, R., Kaltchev, M., Chen, J., Kumpaty, S., Hua, X., Ren, W., Zhang, W.

2018 Pectin, a natural biopolymer mainly derived from citrus fruits and apple peels, shows excellent biodegradable and biocompatible properties. This study investigated the electrospinning of pectin-based nanofibers. The parameters, pectin:PEO (polyethylene oxide) ratio, surfactant concentration, voltage, and flow rate, were studied to optimize the electrospinning process for generating the pectin-based nanofibers. Oligochitosan, as a novel and nonionic cross-liker of pectin, was also researched. Nanofibers were characterized by using AFM, SEM, and FTIR spectroscopy. The results showed that oligochitosan was preferred over Ca2+ because it cross-linked pectin molecules without negatively affecting the nanofiber morphology. Moreover, oligochitosan treatment produced a positive surface charge of nanofibers, determined by zeta potential measurement, which is desired for tissue engineering applications.

Novel bioprinting method using a pectin based bioink

Technology and Health Care,

Banks, A., Guo, X., Chen, J., Kumpaty, S., Zhang, W.

2017 One major challenge of bioprinting is to develop a viable bioink to act as an extracellular matrix. This study investigated a novel method for bioprinting using a pectin based bioink. Besides pectin, Pluronic® F-127 was incorporated into the bioink to obtain the desired shape during the initial bioprinting process at 37∘C. Once an object was printed it was treated with Ca2+ (pectin cross-linker) to create the final tissue/organ structure. The results indicated that pectin/Pluronic® F-127 is a potential bioink. Moreover, this methodology provides a novel and fast approach for bioprinting.

Engineering microvascularized 3D tissue using alginate-chitosan microcapsules

Journal of Biomaterials and Tissue Engineering

Zhang, W., Choi, J.K. and He, X

2017 Construction of vascularized tissues is one of the major challenges of tissue engineering. The goal of this study was to engineer 3D microvascularized tissues by incorporating the HUVEC-CS cells with a collagen/alginate-chitosan (AC) microcapsule scaffold. In the presence of AC microcapsules, a 3D vascular-like network was clearly observable. The results indicate the importance of AC microcapsules in engineering microvascularized tissues—providing support and guiding alignment of HUVEC-CS cells. This provides a promising strategy for constructing vascularized tissues.
