A Dispersion-Dominated Chromogenic Strategy for Colorimetric Sensing of Glutathione at the Nanomolar Level Using Gold Nanoparticles

A dispersion‐dominated chromogenic strategy for glutathione sensing is developed. Glutathione prevents the aggregation of arginine‐modified gold nanoparticles via mercury–thiol interaction, which allows for glutathione sensing at the nanomolar level (10.9 × 10−9 m) with facile operation and naked‐ey...
