GREEN SYNTHESIS AND CHARACTERIZATION OF KNO3 NANOPARTICLES USING C-ROSEUS PLANT EXTRACT

Nanotechnology

A green rapid biogenic synthesis of silver nanoparticles (KNO3NPs) using Catharanthus roseus flower extract was performed. Synthesized nanoparticles were characterized using UV-Visible, Fourier transform infra-red (FTIR) and X-ray diffraction (XRD). The reduction of silver ions to KNO3NPs using C. Roseus extract was completed within 240 mins. The formation of KNO3NPs was confirmed by Surface Plasmon Resonance (SPR) at 442 nm using UV-Vis Spectrophotometer and it is characterized by XRD, Transmission electron microscope (TEM) and Scanning electron microscope (SEM). The morphological studies revealed the spherical shape of the particles with sizes ranging from 16-35 nm and Energy dispersive X-ray (EDX) spectrum confirmed the presence of silver along with other elements in the plant’s metabolite. The extracellular KNO3NPs synthesis by aqueous leaf extract demonstrates ultra-fast, simple and inexpensive method comparable to other methods. The antioxidant assay of the synthesized KNO3NPs indicated that they have a strong antioxidant property as compared to the control. Since these compounds are also safe to use and discharged into the environment, the green KNO3NPs could be considered as an innovative alternative approach for biomedical and nanoscience-based industries.
