Free chlorine ultra-sensitive detection in tap water via an enrichment-sensing process by an interdigitated microelectrode sensor

•An interdigitated microelectrode sensor chip was designed and batch fabricated.•TSAM is proposed to improve the sensitivity of sensor though an enrichment-sensing process.•About 30 times increase in sensitivity of sensor by TSAM is witnessed, comparing with others. Electrochemical free chlorine sen...
