Monolayer immobilization of bacteriorhodopsin on modified polycarbonate surface by using of Langmuir-Blodgett technique

Bacteriorhodopsin (BR) has emerged as an important material for constructing data storage devices due to its unique properties. In this study, BR has been immobilized on modified polycarbonate (PC) surface of compact disk (CD) by using of Langmuir-Blodgett (LB) method. UV/Ozone treatment was used to amplify the immobilization of BR on PC surface. ATR-FTIR and UV-Visible spectroscopy analyses were carried out to study the structure properties of the monolayer. Our results show that an efficient bio surface of PC was fabricated by the Langmuir-Blodgett deposition which is an appropriate candidate to immobilization of BR and formation 0 and 1 bite that relate to bR and P, Q intermediate states in order to construct biomemory.
