Optical trigger based on the molecules of bacteriorhodopsin adsorbed on AgBr nanocrystals

Abstract

It is well known that light absorption triggers transformation chain of bacteriorhodopsin (bR).We propose to use the molecules of bR adsorbed on silver halide crystals to overcome the threshold of spontaneous nucleation from small silver specks to colloidal ones in very short-time interval. Earlier we demonstrated the kinetic curves of the chemical development process for ultrafine-grained emulsion. Colloidal silver particles appeared to lead to effective scattering and absorption of actinic light. Such systems can be considered in the framework of integrated chemical systems.
