Speaker: Dr. David Zamora
Ocular Trauma and Vision Restoration, U.S. Army Institute of Surgical Research, Ft. Sam Houston Texas TX

During operations in Iraq and Afghanistan, 16% of battlefield evacuations were from eye trauma.  If the corneal endothelium is damaged, regenerative potential is limited.  A corneal graft may not be suitable for soldiers with inflamed graft beds, thus an alternative form of therapeutic recovery is needed.  A nanotechnology based approachor guiding cells to the injured area using super paramagnetic iron oxide nanoparticles (SPIONPs) and an external magnetic force was identified.  This work examines the health effects of SPIONPs on bovine corneal endothelial cells (CEC), in the presence and absence of magnetic force, to determine if high SPIONP loading is feasible.  Commercially available CECs were seeded at 21,000 cells per well.  The CECs were exposed to SPIONP concentrations from 0 to 108 nanoparticles per cell.  The viability and structure of CECs was assessed over 3 days.  A two tailed t test showed significant differences (p < .01) between highly SPIONP loaded cells exposed to magnetic force as compared to those not exposed.  The cytoskeleton structure was unaltered and viability was minimally affected.  These results demonstrated cell health was maintained with high SPIONP loading and thus, there is potential for developing an ocular therapeutic platform for externally controlled CEC guidance.

SANTF Purpose:

SANTF aims to provide participants with information on the state of nanotechnology research in Greater San Antonio institutions, presents trends in industry and research universities, informs innovative applications of nanotechnology, information related to current work in progress towards establishing national skills standards, details the involvement and support of national professional societies, and the current technician education programs supported by the National Science Foundation (NSF). The newly formed SANTF strives to build stronger communication and networking opportunities between educational and private businesses, both regionally and nationally; to solidify pipelines in education and stimulate job creation in the Greater San Antonio area in the field of nanotechnology and STEM related fields.    


SANTF brings together researchers, innovators, entrepreneurs, and companies in the Greater San Antonio area working in the areas of nanomaterials and nanotechnology to showcase innovations related to the development and application of nanotechnology and nanomaterials. 


Establish a venue for local researchers, early-stage investors, venture capitalists, and industry leaders to gather and discuss developments in nanotechnology and its applications in the areas of Biomaterials, Energy, Clean Technology, and Sustainability.  

 SANTF brings together major technology players in the area to form strong alliances among the researchers at the University of Texas at San Antonio (UTSA), University of Texas Health Science Center at San Antonio (UTHSCSA), Southwest Research Institute (SwRI), Texas Biomedical Research Institute, Alamo Community Colleges, Trinity University, Texas State University in San Marcos, and other educational institutions. SANTF promotes intellectual creativity in the area of nanotechnology that will create a strong nanotechnology base in San Antonio.    

 The forum is expected to spur productive collaborations among the researchers in Greater San Antonio area and promote innovations leading to scientific discoveries and engineering innovations.  SANTF is committed to enhancing San Antonio’s nanotechnology future and establishing the Alamo City as a global leader in nanotechnology.
