Green Synthesis Silver Nanoparticles using Quercus infectoria Gall

Abstract

In this study, green synthesis of silver nanoparticles (AgNPs) was conducted using Quercus infectoria Gall (QIG) extract with AgNO3/QIG extract volume ratios of 1:1, 4:1, and 8:1. The synthesis successfully resulted in AgNPs, indicated by a color change to orange- brown and analyzed using UV-Vis spectrophotometer, yielding wavelengths in the range of 425 nm to 440 nm. Subsequently, each AgNP was analyzed using a particle size analyzer, resulting in particle diameter sizes of 5.48 nm, 79.88 nm, and 108 nm, respectively, and their stability was analyzed using a zeta sizer, yielding zeta potentials of -52.18 mV, -48.01 mV, and -24.86 mV.
