DOI: 10.1016/j.electacta.2019.07.021
Abstract: Abstract Chitosan-derived molecular films self-assembled on the gold surface were characterized using electrochemical methods combined with quartz crystal microbalance, atomic force microscopy and surface enhanced infrared absorption spectroscopy. We have observed potential-dependent structural transitions, which… read more here.
