In this study, natural or environmentally friendly methods were used to synthesize gold (Au), silver (Ag), and bimetallic nanoparticles from Aegle marmelos seed extract using water (aqueous extract). The evenly distributed nature of the silver nanoparticle was noted by the spectrophotometer data (UV) at max 424nM. FTIR and EDX analysis confirmed that bioactive components present in Aegle marmelos seed aqueous extract were used to form gold, silver, and bimetallic nanoparticles. The formation of Ag nanoparticles was amply demonstrated by the XRD data. The TEM study verified the spherical...
