Novel Bio-Sensor Platform Based on Surface Enhanced Raman Scattering (SERS) Chip

Detailed Technology Description

After several years of research, investigators at UC San Diego’s Jacob’s School of Engineering have developed a portfolio of new technologies to enhance the effectiveness of surface plasmon resonance (SPR) and localized SPR (LSPR) to create sensors capable of identifying single molecules of interest. These sensors have a sensitivity level that is ten orders-of-magnitude greater than commercially available techniques. Included in this body of work are laboratory prototyped nano-hole-array based sensors, including micro-fluidic sample management, illumination optics, single molecule sorting, and novel plasmonic elements capable of sub-diffraction-limit focusing down to 25 nm. The five technology disclosures can be licensed together or separately to realize novel new surface plasmon polariton-based sensors for a variety of applications, including bio-molecule identification.
