SLIPSERS: Single Molecule Detection of Contaminants, Explosives or Diseases Now Possible
Shikuan Yang, Birgitt Boschitsch Stogin and Tak-Sing Wong/Penn State
Artistic illustration showing an ultrasensitive detection platform termed slippery liquid infused porous surface-enhanced Raman scattering (SLIPSERS). In this platform, an aqueous or oil droplet containing gold nanoparticles and captured analytes is allowed to evaporate on a slippery substrate, leading to the formation of a highly compact nanoparticle aggregate for surface enhanced Raman scattering
A technique to combine the ultrasensitivity of surface enhanced Raman scattering (SERS) with a slippery surface, SLIPSERS, invented by Penn State researchers 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.
