research Environmentally Friendly Silver Nanoparticle Synthesis Using Gandaria (Bouea macrophylla) Leaf Waste Extract for Mercury Detection in Facial Cream Products
This study synthesized silver nanoparticles using Gandaria stem bark extract, finding that nanoparticles at a 4% concentration were particularly effective for selectively detecting mercury over lead and calcium, making them suitable as preliminary detection materials for mercury in facial whitening creams.
