Abstract

A large number of cells can be evaluated in terms of their reaction state with molecular reactants under near-field optical conditions in a measuring and evaluation procedure of the invention. Light sources of different aperture diameters in the nano- or micro-range are disposed in a sample platform. The 2D-nano-light source array is embodied by a plurality of near-field light sources which are arranged in mutually juxtaposed relationship in raster form and are excited jointly or in succession. The carrier material used is a semiconductor material.
