UTILIZATION OF MAIZE EXTRACT FOR THE SYNTHESIS AND CHARACTERIZATION OF GOLD NANOPARTICLES AT ROOM TEMPERATURE

In present work, the gold nanoparticles have been prepared through green synthesis using maize extract at room temperature, the maize extract was used as reducing and stabilizing agents for AuNPs (gold nanoparticles), synthesized gold nanoparticles were confirmed by the color change of the aqueous solution, and the PH of the solution was 7.8, after the confirmation, green gold nanoparticles were characterized through various techniques like UV-Visible spectroscopy, FT-IR (Fourier Transform Infrared Spectroscopy), SEM (Scanning Electron Microscopy), TEM (Transmission Electron Microscopy) and EDAX (Energy Dispersive X-ray analysis). UV- Visible spectroscopy was used to determine the green gold nanoparticles, the absorbance peak was observed at 540 nm with the spherical sized gold nanoparticles, and green gold nanoparticles were also confirmed by TEM, and average particle size of gold nanoparticles was observed 30 nm. FT-IR results represent the various phenolic compounds like alkaloids and flavonoids in aqueous solution. The size, shape and other properties were confirmed through Scanning Electron Microscopy and EDAX analysis. Green synthesis of the gold nanoparticles at room temperature is the innovative process for the various biomedical applications in the field of biomedical science and engineering because of the non-toxic property of the green gold nanoparticles.
