Research in our laboratory focuses on the polymer science-medicine interface. Areas of interest include development and modeling of novel drug delivery systems, particularly for the release of insulin and growth factors; designing small-diameter vascular grafts with better compliance; development of novel bioadhesive polymers for oral delivery systems; liquid crystals as smart sensors; the use of nanoparticles as novel therapeutic delivery systems (nanomedicine), tissue markings, DNA delivery.
Dr. Mathiowitz, Professor of Medical Science & Engineering and Director of the Biotechnology Graduate Program in the Department of Molecular Pharmacology and Biotechnology of Brown University, received her Ph.D. in the Department of Structural Chemistry at the Weizmann Institute. At MIT, she continued her research as a postdoctoral student under Dr. Robert Langer. Since then, Dr. Mathiowitz has been involved in research developing oral bioadhesive delivery systems for Proteins and genes, microencapsulation of proteins and genes, and tissue engineering of vascular grafts. She has published 90 papers, has 30 patents, and is a consultant to many biotech companies. She was the founder of Spherics, a previous RI Biotech company and a co-founder of Perosphere.
Research in our laboratory focuses on the interface between polymer science and biology. Areas of interest include:
- Tissue engineering and drug ad gene delivery;
- Development, modeling, and morphological analysis of novel drug delivery systems, particularly for the release of macromolecules, such as insulin and growth factors;
- Synthesis and characterization of biomaterials for drug delivery systems;
- Studies of polymer-protein interactions with emphasis in the development of bioerodible polymers involving the use of mild fabrication techniques;
- Developing of bioadhesive polymers for use as oral delivery systems;
- Design and development of modulated sensors that respond to external stimuli (e.g., light heat).
All of these studies are directed to create easier and more sophisticated ways to administer therapeutic agents into the body exactly where and when they are needed. Most therapeutic peptides and proteins easily degrade when taken orally and are too unstable to withstand packing in slow-release mechanisms - they all require frequent parenteral injections. Understanding the basics of delivery systems is the key for better medications in the future.
Studies of polymer-cell interaction, with particular emphasis on bioadhesion; development of the basic relationship between polymer structures (molecular and morphological) and living tissue; surface modification for enhancement of cell adhesion, an area of particular importance in the development of oral delivery systems as well as small vascular grafts.
Development of theoretical and experimental procedures to process microcapsules based on biomaterials; processing of polymeric composites based on microencapsulation. A wide range of polymers and polymer blends are investigated, including interpenetrating networks, amorphous, semicrystalline, and liquid crystal polymers.
