Abstract
A Raman scattering spectrographic analyzer wherein a microscope objective is adapted to view single bio-specimens on a substrate having monodispersed-sized metal particles. A defined wavelength of radiation is applied through the microscope and returning radiation resulting from Raman scattering by bio-specimens is applied to a spectrometer operative to provide a signal corresponding to the wavelength components in said Raman scattered or shifted radiation. The spread spectrum of the Raman shift is analyzed for identification of a bio-specimen.
