Reversible photoisomerizable monolayers for the transduction of optical signals

Bioelectronic devices based on te photostimulation of the chemical and physical properties of molecules are presented. Assemblies consisting of photoswitchable biomaterials and conducive interfaces have opened new avenues in the design of architectures for molecular devices. Photosensitive self assembled monolayers on electrode surfaces provide the means for the nanoscale design of optoelectronic systems for information storage and processing, signal amplification, and biosensor devices. Recent progress in the area is reviewed.
