Smartphone-based fluorescence detection of 2,4-dichlorophenoxyacetic acid using ImageJ analysis on a molecularly imprinted membrane/carbon-dot system via a Schiff-base method.

The persistent presence of 2,4-dichlorophenoxyacetic acid (2,4-D) in aquatic ecosystems poses a significant risk to both the environment and human health. This study presents a novel fluorescence-based sensor designed to detect ultra-trace amounts of…
