Abstract:
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-eye readout.
