Light-Sensitive Colored Protein, Bacteriorhodopsin

Bacteriorhodopsin, a membrane protein that uses light to translocate protons.

Translocation in colored light.

The translocation of (14)C-photosynthate in detached blades of sugarcane was studied under illumination from red, green, blue, and cool-white fluorescent lamps; under far-red illumination from the sun, and from incandescent lamps; and in total darkness.The percentage of basipetal translocation and the accumulation against the concentration gradient were stimulated by light from the red or blue ...

Color sensitive retina based on bacteriorhodopsin.

Bacteriorhodopsin (BR), a membrane protein of a microorganism Halobacterium salinarium has been studied since the 80's as a potential material for information technology. The information processing applications of BR employ either photochromic or photoelectric properties of the protein. In this study we discuss about design principles and describe our study of the use of bacteriorhodopsin as a ...

Normalized Model of Traffic Light Traits Based on Colored Pixels

Nowadays, because of the growing numbers of vehicles on streets and roads, the use of intelligent controlsystems to improve driving safety and health has become a necessity. To design and implement suchcontrol systems, having information about traffic light colors is essential. There are the wide variety oftraffic lights in terms of light intensity and color. Therefore it seems that design and ...

Light-Controlled Spin Filtering in Bacteriorhodopsin

The role of the electron spin in chemistry and biology has received much attention recently owing to to the possible electromagnetic field effects on living organisms and the prospect of using molecules in the emerging field of spintronics. Recently the chiral-induced spin selectivity effect was observed by electron transmission through organic molecules. In the present study, we demonstrated t...
