Single molecule detection of contaminants, explosives or diseases now possible

A technique that combines the ultrasensitivity of surface-enhanced Raman scattering (SERS) with a slippery surface will make it feasible to detect single molecules of a number of chemical and biological species from gaseous, liquid or solid samples. This combination of slippery surface and laser-based spectroscopy will open new applications in analytical chemistry, molecular diagnostics, environmental monitoring and national security.
