Overview

Experimental study demonstrates sensitive colorimetric mercury detection in aquatic products using portable hydrogel kits, highlighting practical on-site food safety monitoring.

Key Points

To develop an efficient, simple, and portable colorimetric hydrogel platform for monitoring toxic mercury ion contamination in water and aquatic products.
Synthesized silver nanoparticles (Qu-CD-AgNPs) using an inclusion complex of quercetin and β-cyclodextrin.
Embedded the nanoparticles and 3,3′,5,5′-tetramethylbenzidine (TMB) substrate into a hydrogel matrix to establish a colorimetric assay.
Integrated the hydrogel assay with a custom portable smartphone application designed for real-time RGB color value quantification.
Mercury ions interacted with the nanoparticles to form an Ag–Hg alloy, substantially accelerating oxidase-like oxidation of TMB to produce a concentration-dependent color transition.
The sensor demonstrated a linear detection range from 3 to 100 μM and achieved a limit of detection of 0.023 μM.
The hydrogel platform exhibited strong selectivity and anti-interference capacity against other common metal ions.
