Green Synthesis of Silver Nanoparticles Using Aqueous Extract of Vachellia xanthophloea and Their Potential Use for Antibacterial and Sensing of Mercury Ions

Colorimetric Sensing of Mercury in Aqueous Solutions Using Silver Nanoparticles Prepared from Synadenium glaucescens Root Aqueous Extract

“…The appearance of the SPR absorption band was attributed to the mutual vibrations of electrons in nanoparticles in resonance with light waves [9]. The appearance of the SPR absorption band at 420 nm was also reported in other prepared silver nanoparticles [11,12]. The appearance of the symmetrically shaped surface plasmon resonance in the spectrum suggests that the prepared silver nanoparticles were spherical with a uniform distribution.…”
