Development of Novel Fluorescent Light-up Pb2+ Sensor Using G-quadruplex Complex with Modified Thioflavin T We developed a novel, cost-effective fluorescent light-up biosensor for Pb²⁺ detection using a label-free G-quadruplex combined with modified Thioflavin T (ThT) derivatives, utilizing the unique K⁺-Pb²⁺-G-quadruplex conformation.

Reduced graphene oxide (rGO) and MoS , the most representative two-dimensional (2D) materials, are receiving significant attention for the fabrication of sensing devices owing to their high surface area, many abundant sites, and excellent mechanical flexibility. Herein, we demonstrated chemoresistive humidity sensors with fast response, excellent selectivity, and ultrahigh sensitivity based on 2D rGO and 2D MoS hybrid composites (RGMSs).

Chemoresistive gas sensors based on two-dimensional (2D) materials including graphene-based materials have attracted significant research interests owing to their potential use in the next-generation technologies including the Internet of Things (IoT).
