Nano-assembled supramolecular films from chitosan-stabilized gold nanoparticles and cobalt(II) phthalocyanine

+ groups from Chit. Supramolecular interaction was observed for multilayer films of Chit- AuNPs/CoTsPc, and the AuNPs influenced the redox properties of CoTsPc. The presence of the nanoparticles not only increased the electroactive area of the electrodes, but also the rate of charge-transfer, suggesting that this material is a very promising candidate for further applications in electrochemical devices.
