This paper describes the construction of a photogenerated electron transfer system based on photosystem I (PSI) and modified molecular wires. Gold electrode surfaces were functionalized with sodium 3-mercapto-1-propanesulfonate and the 2,2′-dimethyl-4,4′-bipyridine cation to form a self-assembled monolayer, which enabled the subsequent immobilization of PSI. A higher photocurrent was observed in the...
We report on the first successful output of electrons directly from photosystem I (PSI) of thermophilic cyanobacteria to the gate of a field-effect transistor (FET) by bypassing electron flow via a newly designed molecular wire, i.e., artificial vitamin K 1 , and a gold nanoparticle; in short, this newly manufactured photosensor employs a bio-functional unit as the core of the device. Photo-electrons...
