Novel approach to gold ion detection in aqueous solutions using silver nanoparticles synthesized from the seed extract of mangrove associate plant Thespesia populnea

This study presents a novel, eco-friendly colorimetric sensor for the sensitive and selective detection of gold(III) ions, utilizing silver nanoparticles synthesized using Thespesia populnea seed kernel extract (AgNP-TPK). The green synthesis yielded stable nanoparticles, confirmed by UV–Vis, HR-TEM...
