Dopamine functionalized carbon nanoparticles (CNPs) that can act as efficient photoinduced electron donor-acceptor systems depending on the pH of the medium have been synthesized. In acidic media, dopamine on CNPs exists as hydroquinone and serves as an electron donor while under alkaline conditions the corresponding quinone form of dopamine serves as a strong electron acceptor. Application of external NADH to the system can invert the donor-acceptor roles under alkaline conditions.
