Penn State researchers have invented a way to detect single molecules of a number of chemical and biological species from gaseous, liquid or solid samples, with applications in analytical chemistry, molecular diagnostics, environmental monitoring and national security.
The invention is called SLIPSERS, an acronym combining “slippery liquid-infused porous surfaces” (SLIPS) and surface enhanced Raman scattering (SERS).
Single-molecule detection of contaminants, explosives or diseases now possible
