Inventors: Igor Smolyaninov, Christopher Davis, Yu-Ju Hung
The fundamental technology is a dielectric grating, or an array of dielectric gratings, (periodic patterns with various symmetries and periodicities) that are placed on top of a thin metal film. These structures allow the selective excitation of surface plasmons that excite fluorosphores near the metal surface. This selective excitation can be spatially and wavelength controlled, and the plasmon excitation boosts the intensity of the fluorescence signal. Various selective binding agents that can be selectively fluorescently tagged, or other chemically modifiable fluorosphores, are placed on top of the dielectric gratings.
This invention crosses two major disciplines, those being plasmonics and micro biology. The invention is currently a product of the plasmonics team at UMCP and there will need to be considerable assistance from a microbiology contributor yet to be identified.
The final product is considered to be easy to put into mass production, however, this will need to be verified by an outside partner with experience in similar production issues such as the manufacture of gene chips.
Initial views of this technology indicate that it has definite commercial possibilities. Its strengths are:
It also will provide the foundation for meeting the requirements published by the EPA for future Biowatch sensor deployments. Those requirements are:
