Photo-stimulated self-powered electrochemical system for DNA release

The DNA-release activated by light in the self-powered bioelectronic system has been studied. The system was composed of two connected electrodes: one photo-active electrode was modified with photosynthetic thylakoid membranes and another electrode was modified with O2-reducing bilirubin oxidase and...
