ABSTRACT:
A Raman imaging and sensing apparatus is described. The apparatus employs a nanoantenna structure which includes a metal tip spaced from a metal surface or particle. A light beam impinges upon the nanoantenna and causes plasmon resonance. The plasmon resonance excites a sample resulting in dramatically enhanced Raman scattering of the sample. The Raman scatter is collected by a spectrophotometer which provides an output signal indicative of the composition of the sample.
