Fluorescent polydopamine nanoparticles as a nanosensor for the sequential detection of mercury ions and l-ascorbic acid based on a coordination effect and redox reaction

Abstract

A novel fluorescence nanosensor using intrinsic fluorescent polydopamine nanoparticles as an effective signal reporter was constructed for simple, rapid and sequential detection of Hg²⁺ ions and l-ascorbic acid based on a coordination effect and redox reaction.
