Sensitive elements based on bacteriorhodopsin for fiber-optics sensors of chemical components [PDF]
The sensitive thin film elements based on bacteriorhodopsin in polymeric matrixes for the multichannel fiber-optical sensor system of measurement of chemical composition of gas mixtures are offered. It is shown, that modification of films compositions

In the purple membrane (PM) of Halobacterium salinarum is present a phospholipid dimer consisting of sulfo-triglycosyl-diether (S-TGD-1) esterified to the phosphate group of phosphatidic acid (PA), i.e., S-TGD-1-PA, called glycocardiolipin (GlyC ...

SERS OF BACTERIORHODOPSIN WITH OUT-DIFFUSED SILVER NANOISLANDS [PDF]
We present the studies on surface-enhanced Raman spectroscopy (SERS) of bacteriorhodopsin in purple membranes using self-assembled silver nanoisland films for Raman signal enhancement.

Bacteriorhodopsin (BR) functions as a light-driven proton pump that transitions between different states during the photocycle, such as all-trans (AT; BR568) and 13-cis, 15-syn (CS; BR548) state and K, L, M1, M2, N, and O intermediates. In this study, we

Zinc oxide (ZnO) and bacteriorhodopsin (bR) hybrid nanostructures were fabricated by immobilizing bR on ZnO thin films and ZnO nanorods. The morphological and spectroscopic analysis of the hybrid structures confirmed the ZnO thin film/nanorod growth and ...

Picosecond events in the photochemical cycle of the light-driven chloride-pump halorhodopsin [PDF]
The early events in halorhodopsin after light excitation are studied with picosecond time resolution. Absorption and fluorescence measurements show that the electronically excited state of the incorporated retinal has a lifetime of 5 ps. Within that time
