Abstract

Electrostatic self-assembled films of deoxyribonucleic acid (DNA) and diazoresin(DAR) were fabricated on substrates. Under irradiation, photoreaction occurring between adjacent layers was confirmed by UV-Vis and Fourier transform infrared(FTIR) spectra, which covalently attached DNA to DAR in the multilayer. The stability of the multilayer was greatly improved, which was confirmed by etching in NaCl solution and monitored by UV-Vis and scanning force microscopy (SFM).
