Bacteriorhodopsin-Novel biomolecule for nano devices

Abstract

The aim of this article is to provide insight on the use of a biological molecule-bacteriorhodopsin (bR) having all the basic properties necessary for the assembly of nanoscale electronic devices. Recent developments made during last decade supported by key references are reviewed in this contribution. Major emphasis on bR-based observations conducted in our laboratory has been elaborated. Important issues concerning structure, widely accepted photocycle of bR has been summarized. The possibility of nano-devices emanating from this biomolecule is briefly presented. © 2005 Elsevier B.V.
