Abstract: Green: Curcuma Longa

This document summarizes a study on the biosynthesis of silver nanoparticles using Curcuma longa (turmeric). Key findings include: - Silver nanoparticles were successfully synthesized using a simple and eco-friendly method involving aqueous silver nitrate reacted with a C. longa extract acting as both reductant and stabilizer. - Characterization methods like UV-Vis spectroscopy, XRD, TEM, SEM, EDX, and FTIR confirmed the formation of crystalline silver nanoparticles approximately 6.3 nm in size with a face-centered cubic structure. - The biosynthesis of silver nanoparticles using C. longa extract provides a green alternative for production and has applications in biomedical and nanotechnology industries.

biosynthesized nanoparticles, especially the noble metals, have mainly been studied because of
from aqueous their strong optical absorption in the visible region caused by the collective
silver nitrate excitation of free-electron gas.2
through a simple Among noble metal nanoparticles, silver nanoparticles (Ag-NPs) have a wide
