Abstract

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 nanoparticles functionalized with molecules changing their charge upon pH variation. When the photo-electrode was illuminated, it produced current resulting in O2 reduction and local pH change at the releasing electrode. The interfacial charge was changed from positive, when negatively charged DNA was loaded, to negative, when the DNA was repulsed and released.
