Paper Abstract

The structure of multilayer Langmuir-Blodgett (LB) films made of protein (Bovine serum albumine)-co-proporphyrin(III) conjugate was investigated by means of fluorescence microscope coupled with the time-correlated single photon counting registration system. The map of coproporphyrin fluorescence from the surface of protein LB-films was measured with picosecond time resolution and spatial resolution 15 micrometers . The sample area 240 X 240 micrometers was irradiated step by step by a focused beam of Nd:YAG laser with an accumulation time of 3 sec per point. There were two different kinds of samples: those with regular and those with irregular distribution of fluorescent labels over the sample.
