中文摘要	we initiate a systematic exploration of a natural polymer, chitosan, as a structural material for designing functional layers on electrode surfaces in this work. au colloid films are organized on chitosan layer by adsorption. we have successfully constructed a multilayer an nanoparticle assembly through electrostatic interactions on chitosan functionalized quartz substrates by the alternate treatment of the substrate with solution of citrate-stabilized gold nanoparticles (negatively charged) and chitosan solution (positively charged). the resulting substrates were characterized by uv-vis spectrometry, atomic force microscopy (afm), and electrochemical impedance spectroscopy (eis) measurements. these assemblies of colloid an multilayer are highly stable, and can be kept for a long time in distilled water, only being removed by scratching or extreme electrochemical conditions.
