“…Due to the biocompatibility of the polymers used, the ability to encapsulate and protect purple membrane make these systems attractive for delivery and to use it for example as biosensors [57] , [58] . Finally, bacteriorhodopsin-based materials have a broad potential application in photonics [59] . Therefore, we believe that the presented insights, particularly the possible synthesis route of bR-doped nanogels and the theoretical analysis brings the possibility to fabricate nanodevices that could give solution to applications such as organic solar cells, nano optical-switches or optical memories [60] , [61] .…”

We theoretically and experimentally analyze the formation of thick Purple Membrane (PM) polyacrylamide (PA) films by means of optical spectroscopy by considering the absorption of bacteriorhodopsin and scattering. We have applied semiclassical quantum mechanical techniques for the calculation of absorption spectra by taking into account the Fano effects on the ground state of bacteriorhodopsin. A model of the formation of PM-polyacrylamide films has been proposed based on the growth of polymeric chains around purple membrane. Experimentally, the temporal evolution of the polymerization process of acrylamide has been studied as function of the pH solution, obtaining a good correspondence to the proposed model. Thus, due to the formation of intermediate bacteriorhodopsin-doped nanogel, by controlling the polymerization process, an alternative methodology for the synthesis of bacteriorhodopsin-doped nanogels can be provided.

“…Bacteriorhodopsin (BR), a photochromic biological protein found in the purple membrane of the bacterium Halobacterium salinarum, is one of the promising candidates for all-optical Boolean logic gates because of its unique optical properties, e.g. large optical nonlinearity, high quantum efficiency of the photoreaction, fast response, high spatial resolution, excellent stability and fatigue resistance [8][9][10][11]. Various methods of optical logic operation based on BR films have been proposed.…”

All-optical logic gates based on photoinduced anisotropy of bacteriorhodopsin (BR) film are proposed. The photoinduced anisotropy in BR film, which arises from the selective absorption of BR molecules to polarized light, can be controlled by changing the amplitudes and polarizations of exiting beams. As a consequence, the polarization of the probe light passing through the BR film can be controlled by the polarization of the exiting beam. Based on this property, a novel scheme of all-optical logic gates, such as AND, OR, XOR and NOT, has been implemented via the pump-probe technique. A theoretical model for the all-optical logic gates is proposed, and the theoretical predictions are demonstrated with the experimental results.

Laser intensity induced nonlinear absorption based photonic switching in pharaonis phoborhodopsin (p pR) protein molecules has been analyzed theoretically, using a rate equation approach. The probe beam transmissions at 560 and 390 nm, respectively, have been shown to be switched by nanosecond pump pulse excitation at 498 nm. Fast digital operation with ∼250 ns switching time is achieved by utilizing its K ‐intermediate state population changes. The presently observed switching speed (∼250 ns) in p pR is much higher in comparison to earlier reported values in milliseconds and seconds in different rhodopsin protein molecules. Analysis provides the scheme for fast photonic switching with slow photochromic materials having some fast energy states. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
