Abstract

Techniques of coherent nonlinear spectroscopy (second harmonic generation and third harmonic generation) are combined with near-field scanning optical microscopy for imaging selected chemical and physical environments in biological matter on a nanoscopic scale. Resonant enhancement of nonlinear signals is utilized as a method of producing chemically selective contrast while the order of the process provides environmental selectivity. Systems studied include natural killer cells and erythrocytes.
