Electrostatic self-assembly multilayer films have been successfully fabricated from a C-60-ethylenediamine adduct (C-60-EDA), and DNA. Under visible light irradiation, the DNA is cleaved and the films are destroyed. The photo-induced reaction follows a direct electron-transfer mechanism. A high oxygen concentration in the solution enhances the reaction, while separation of C-60-EDA and DNA retards the reaction dramatically.
