Synthesis of biogenic silver nanoparticles using Piper chaba leaf extract for dual-functional applications: Hg( ii ) sensing and catalysis

Piper chaba leaves extract-assisted silver nanoparticles (AgNPs) are crystalline, spherical, and size of 20 nm. They effectively detect Hg( ii ) through visible color change and catalyze the reduction of 4-nitrophenol and degradation of dyes.
