High-selectively wearable Bi-based smartsensor constructed via template sacrifice for in-site heavy metals monitoring

Abstract

A flexible bismuth (Bi)-based smartsensor capable of simultaneously detecting Cd2+, Tl+, and Pb2+ is first proposed. Fabricated via template-assisted electrodeposition method, this novel sensor demonstrates excellent selectivity in distinguishing these heavy metal ions (HMIs). The developed platform holds broad application prospects for on-site HMIs monitoring.
