Pulsed electrochemical detection of proteins using conducting polymer based sensors

These studies reveal that sensitive responses for proteins can be generated at selected conducting polymer electrodes using flow-injection analysis (FIA) and pulsed electrochemical detection. The responses observed are dependent on the nature of the polymer, the nature of the electrolyte anion/cation as well as on the electrolyte concentration and pH. These factors can be used to modify selectivity. Detection limits in the order of nanomolar have been estimated.
