Abstract
A novel platform for transient photodetector component screening has been developed whereby an optical fiber tip serves as the counter electrode when placed in a variety of dielectric media, connected to a photoresponsive working electrode. The soft processing conditions allow for ubiquitous photodetection for organic and biological systems.

Abstract
Retinal proteins (~rhodopsins) are photochemically reactive membrane-embedded proteins, with seven transmembrane α-helices which bind the chromophore retinal (vitamin A aldehyde). They are widely distributed through all three biological kingdoms, eukarya, bacteria and archaea, indicating the biological significance of the retinal proteins. Light absorption by the retinal proteins triggers a photoisomerization of the chromophore, leading to the biological function, light-energy conversion or light-signal transduction. This article reviews molecular and evolutionary aspects of the light-signal transduction by microbial sensory receptors and their related proteins. This article is part of a Special Issue entitled: Retinal Proteins - You can teach an old dog new tricks.

Abstract
Light is one of the most important energy sources and signals providing critical information to biological systems. The photoreceptor rhodopsin, which possesses retinal chromophore (vitamin A aldehyde) surrounded by seven transmembrane alpha-helices, is widely dispersed in prokaryotes and in eukaryotes. Although rhodopsin molecules work as distinctly different photoreceptors, they can be divided according to their two basic functions such as light-energy conversion and light-signal transduction. Thus rhodopsin molecules have great potential for controlling cellular activity by light. Indeed, a light-energy converter channel rhodopsin is used to control neural activity. From 2001, we have been working on various microbial sensory rhodopsins functioning as light-signal converters. In this review, we will introduce rhodopsin molecules from microbes, and will describe artificial and light-dependent protein expression system in Escherichia coli using Anabeana sensory rhodopsin (ASR). The newly developed tools would be widely useful for life scientists.
