Abstract:
Nanoparticles are considered to be the pre-eminent component of the rapidly advancing field of nanotechnology. In recent years, the green synthesis of silver nanoparticles using various plant extracts has attracted great attention. The use of nanoparticles in the field of medicine is increasing in the present world of nanotechnology. Green synthesis of nanoparticles has attracted scientist as a safe, easy and cheap mode of nanoparticles ion in the developing and also in developed countries. In the present study, the silver nanoparticles were synthesized using the Aloin derivative extracted from Aloe barbadensis, a medicinal plant. The plant extract act as a reducing agent as well as a capping agent. The bio reduced silver nanoparticles were characterized using UV-Visible spectroscopy, SEM. A broad SPR band was observed at 440nm in the UV-Visible spectra. X-ray diffraction revealed their crystalline nature. Scanning electron microscope showed spherical shaped and monodispersed nanoparticles. The antifungal and antioxidant activity of the synthesized silver nanoparticles were also examined.
