SANTF Networking Lunch Series

Dr. Katheryn Mayer

"Label Free Detection of Single Protein Molecules via Localized
Surface Plasmon Resonance Sensing"

Wednesday, September 24, 2014

11:30 am to 12:45 pm

The September SANTF Networking Lunch will be held at the UTSA Faculty Center 4th Floor of the John Peace Library (JPL).

Speaker: Dr. Kathryn (Katie) Mayer, Ph.D.
Assistant Professor, Department of Physics and Astronomy, UT- San Antonio

Localized surface plasmon resonance (LSPR) sensing is an optical, label-free technique which exploits the principle that changes in refractive index near the surfaces of metal nanoparticles cause measurable shifts in the particles’ extinction spectra. By utilizing metal nanoparticles functionalized with a capture layer, we developed sensitive and specific immunoassays based upon LSPR. An LSPR immunoassay can be carried out at the single-particle level by the use of dark-field scattering spectroscopy, revealing that it is possible to measure the spectral shift due to single molecule unbinding events. Because this technique is label-free and is able to capture phenomena over long time scales, it can provide complementary information to other single molecule methods. Long-term goals include the extension of single-molecule LSPR sensing to the study of protein conformational changes, and the combination of LSPR spectral measurements with spatial data from subdiffraction- limited localization microscopy.

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.
