Dr. Betancourt obtained her B.S. degree in chemical engineering from Texas A&M University in 2002, and her M.S. and Ph.D. degrees in biomedical engineering from The University of Texas at Austin in 2005 and 2008, respectively. Dr. Betancourt is an Associate Professor in the Department of Chemistry and Biochemistry and a faculty member of the Materials Science, Engineering, and Commercialization Program at Texas State University. Dr. Betancourt leads the research of the Biomaterials and Nanomedicine Laboratory, which focuses on the development of functional polymeric nanostructures for the detection, monitoring, and treatment of cancer and other diseases.

Prior to joining Texas State University in 2011, Dr. Betancourt worked at InnoSense LLC, a technology company serving the aerospace, energy, defense, and health care market. During her three-year tenure at InnoSense, Dr. Betancourt held the positions of Research Scientist, Team Leader, and Deputy Director-R&D. At InnoSense, Dr. Betancourt was responsible for developing novel technologies in the areas of biosensors, biomaterials, therapeutics, theranostics, contrast agent, drug delivery, and specialty materials. She secured over $1 million for support of R&D of biomedical and specialty material technologies from federal agencies.

Dr. Betancourt’s work has been documented in twenty-five peer-reviewed publications, two review articles, two book chapters, and numerous professional presentations.

Research Description

Dr. Betancourt’s research focuses on capturing the promise of nanomaterials for the development of new strategies for the detection and treatment of diseases. Specifically, her group develops functional nanostructures that can act as highly specific contrast agents for bioimaging, in vitro and in vivo biosensors, targeted and intracellular drug delivery systems, and externally controlled therapeutic systems. These responsive nanomaterials incorporate functional nucleic acid linkers, enzymatically cleavable linkers, polyelectrolytes, synthetic polymers and amphiphilic copolymers to mediate physico-chemical changes in the polymeric networks upon interaction with target molecules or external stimuli, leading to the desired material response. Work in the laboratory encompasses the synthesis and characterization of copolymers and nanoparticles, in vitro confirmation of stimuli-responsive behavior, and the evaluation of the particle functionality on cultured human cells. Dr. Betancourt’s group collaborates with academic and industrial researchers for preclinical evaluation of the compatibility and efficacy of the developed biomaterials and technology transfer. Current projects in Dr. Betancourt’s laboratory include the development of: (1) aptamer-based responsive nanostructures that can be activated by disease-specific molecules, and on the study of the applications of these functional materials in targeted drug delivery, bioimaging, and biomolecular sensing; and (2) nanoparticle-based agents for photothermal therapy, chemotherapy, and immunotherapy.
