Abstract
Here, a method of preferential adsorption of dyes on micro patterned molecular monofilms is presented. Therefore, micro spot arrays consisting of different types of monofilms are exposed to dye solutions. After this immersion, the chips are rinsed in a solvent, which differentiate the desorption rate from molecular monospots and their surroundings. The degree of adsorption depends on the dye properties. Charge, polarity and H-bridges seems to play the major role in the differential adsorption. In result, the pattern of molecular monofilms can easily be identified by intensity differences of fluorescence radiation from chip surfaces.
