摘要: We demonstrate a heavy metal-ion sensor for drinking water analysis using conducting polymer nanojunction array. Each is formed by bridging pair of nanoelectrodes separated with small gap (<60nm) electrodeposited peptide-modified polyanilines. The signal transduction mechanism the based on change in conductance as result conformational changes induced chelating peptide. allows real-time detection Cu2+ and Ni2+ at ppt range.
