Abstract

The development of a scalable, low-cost, and versatile sensor platform for the sensitive and rapid detection of heavy metal ions (HMIs) is of great interest to human health and the global ecosystem. Here we report on an all-solution method to fabricate a sensor platform based on nanostructured conductive polyaniline (PANI) in which the electrode materials were functionalized with L-Cysterine (L-Cys). And based on this platform, we realized the simultaneous detection of Pb²⁺ and Cd²⁺ with the detection limit of 11.6 nM and 10.5 nM, respectively. It proves that the proposed sensor has good performance, and broad application prospects in HMIs detection.
