We would like to whole-heartedly congratulate Dr. Vinoy Thomas on well deserved attainment of tenure and being promoted to Associate Professor in the Department of Materials Science and Engineering.
CONGRATULATIONS Dr. Thomas
A UAB team led by Dr. Vinoy Thomas, Department of Materials Science & Engineering, has surface engineered 3D Printed polymeric soft biomaterial scaffolds by an in-situ robust synthesis of nanoparticles using low temperature dusty plasma.
The proof-of-concept communication published in ACS Applied Nano Materials, reports a rapid and easy method for nanoparticles (SiNp) synthesis from a liquid precursor into dusty plasma and deposition of them onto 3D printed polymer. “Non-thermal plasma has emerged as a viable method for surface engineering soft materials and biomaterials”, says Dr. Vineeth Vijayan, (first author of the publication), “and we have successfully utilized non-thermal plasma for making super-hydrophilic and blood-friendly materials surfaces in our previous publication in Journal of Materials Chemistry”.
As part of the NSF supported EPSCoR collaborative CPU2AL program, the new method we reported has many appealing attributes:
The future aspects of this present work will deal with (I) functionalization and attachment of SiNp with biochemical moieties by using volatile amino acids in the plasma phase and (II) strategies for preparation titanium dioxide nanoparticles and nanowires via plasma process which in turn could be used for decontaminate corona virus during the current COVID-19 pandemic.

NSF Faculty Early Career Development Award (CAREER)
“CNMB member and a faculty member in the UAB Department of Chemistry Dr. Eugenia Kharlampieva has been awarded a National Science Foundation (NSF) Faculty Early Career Development Award entitled “CAREER: Shape Responses of Ultrathin Hydrogel Microcapsules” for a five year period 2014-2019. This is one of the National Science Foundation’s most prestigious awards in support of junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations”
CNMB Member Dr. Claudiu T Lungu Awarded a National Institute for Occupational Safety & Health Grant (CDC/DHHS R21, Total amount for two years: 09/01/2013 – 08/31/2015: $398,672)
The goal of this study is to develop a new technique that allows accurate sampling of gases and vapors at low levels.
Dr. Lungu is investigating a new process of using pulsed visible light to release chemicals from new substrates based on carbon nanotubes. These substrates will be used in air sampling devices for volatile organic compounds and gases for workplace or environmental monitoring. This research could potential lead to a new generation of air samplers that may be faster, cheaper, and more sensitive than the currently available models.
Dr. Eugenia Kharlampieva Awarded a National Science Foundation Biomaterials Grant
Immunomodulatory Ultrathin Multilayer Coatings for Pancreatic islet Transplantation NSF-DMR1306110, program of Biomaterials (BMAT)
This grant will supports the development of a novel type of cytoprotective material with controlled immunomodulatory and inflammatory responses to be used for cell-basedtransplantation therapy for diabetic recipients. This project is in collaboration between departments of Chemistry (Eugenia Kharlampieva, PI) and Microbiology (Hubert Tse, coPI). Although transplantation of pancreatic islet cells has emerged as a promising treatment for Type 1 diabetes, its clinical application remains limited due to adverse effects of immunosuppression and declining allograft function. The awarded project will develop a preclinical approach to preserve islet viability and function during culturing and transplantation by protecting pancreatic islets (cell clusters) with a novel polymer coating. These coatings will be designed through hydrogen-bonded assembly of cytocompatible macromolecules with antioxidant and anti-inflammatory characteristics. This project is particularly timely since current islet encapsulation systems are challenging for transplantations due to high cytotoxicity and the requirement for large injection volumes. The design of novel immunoprotective materials will open new prospects for developing biomaterials with unique characteristics having applications in various bio-related areas such as bioengineering and tissue engineering. The awarded project will develop interdisciplinary collaborative research which should stimulate awareness of the needs of the UAB biomedical research community for specialized polymer-based biomaterials as novel platforms for cell transplantation therapy.
