Bioinspired gold nanoparticles-based colorimetric nanosensor for detection of antimony in plastic bottled water

It is reported that antimony (Sb), a toxic metal classified as potentially carcinogenic, migrates from plastic bottles into bottled water. Here, bioinspired colorimetric sensor based on green synthesized gold nanoparticles (AuNPs) using unchewable part of Khat leaf ( Garaba ) extracts were developed...
