Abstract : The present study aims towards the green synthesis of ZnO NPs and study their antimicrobial property. The nanoparticles were synthesized at room temperature using fresh aqueous extract of leaves of Aloe barbadensis (Aloevera). The use of plants for green synthesis are cost effective and eco friendly. Different characterization of the nanoparticles were done using UV-Visible spectroscopy, excitonic peak is observed around 200 nm for ZnO NPs, the Fourier Transform Infrared Spectroscopy (FTIR) is carried out which shows the presence of alcohol and ketone in the synthesized
ZnO NPs,X-Ray Diffraction (XRD) structure shows that the particles to be crystalline in nature.Antimicrobial activity was observed by using Agar Disc Diffusion method against Escherichia coli. By comparing the diameter of inhibition zone of ZnO NPs with respect to antibiotics, we analyzed that ZnO NPs is more effective than Ofloxacin.
Keywords : green synthesis of nanoparticle, Aloe barbadensis (Aloe vera) extract, characterization, antimicrobial analysis
