A traffic light-type sensitive visual detection of mercury by golden nanoclusters mixed with fluorescein
Abstract
A novel colorimetric sensor based on red-emitting bovine serum albumin‑golden nanoclusters (BSA-AuNCs) and green-colored fluorescein that exhibited traffic light-type color change was developed for ratiometric and visual detection of mercury (Hg). In the presence of Hg2+, the red fluorescence from BSA-AuNCs was quenched while the green fluorescein was inert thus as a reference. And it presented traffic light-type (red, yellow and green) color in...
