Bacteriorhodopsin—Perspective biomaterial for molecular nanophotonics

Results of investigation of photochromic protein bacteriorhodopsin (BR) extracted from cellular membranes of Halobacterium salinarum are represented. Basic processes and original approaches of neural networks realization based on bacteriorhodopsin in composition of multilayer structures. Requirements of BR-containing functional films are determined and results of investigation of layers modifications are represented for the purpose of stabilization of extremely high photochromic sensitivity of BR-containing media. The modification of BR-films using bifunctional crosslinking reagents to increase of technological parameters of BR is applied. The influence of 1,4-diaminobenzene, glutaric dialdehyde and lysine on photochromic properties of the bacteriorhodopsin films is investigated. Shown that addition of bifunctional crosslinking reagents increase technological parameters of materials based on bacteriorhodopsin.
