Biosynthesis and Characterization of Titanium Dioxide Nanoparticles Using Pithecellobium Dulce and Lagenaria Siceraria Aqueous Leaf Extract and Screening their Free Radical Scavenging and Antibacterial Properties

Full Text PDF


The recent development and implementation of new technologies have led to new era, the nanorevolution which unfolds role of plants in bio and green synthesis of nanoparticles which seem to have drawn quite an unequivocal attention with a view of synthesizing stable nanoparticles. In this present work, we have compared titanium dioxide nanocrystals synthesized by both chemical method and biological method from Titanium tetra isopropoxide as precursor. The biological method was performed by using the aqueous plant extract of Pithecellobium dulce and Lagenaria siceraria. The synthesized nanocrystals were characterized by FTIR Spectroscopy, Scanning Electron Microscopy (SEM), Energy Dispersive Xray (EDAX), Transmission Electron Microscope (TEM) and X-ray diffraction (XRD) techniques and also Antioxidant assay and antimicrobial test were performed to evaluate its biological behaviour. The nanocrystals synthesized by biological method were found to have higher antioxidant potential, antimicrobial activity than chemically synthesized.
