Antibacterial Activity of Silver Nanoparticles Synthesized from Aloe Vera Extract

Abstract

Material science has advanced significantly due to nanotechnology, which enables researchers to work with materials at the nanoscale to produce novel goods. It has been suggested that using plant extract nanoparticles biosynthesis is an economical, and environmentally benign process. Despite various chemical and physical approaches, green nanomaterial synthesis is the most contemporary. We used the Aloe vera plant to synthesize silver nanoparticles (AgNPs) and tested their antibacterial characteristics. UV-Vis spectroscopy, Scanning Electron Microscope (SEM), and X-ray diffraction were used to analyze the produced AgNPs. The XRD peaks, which were indexed, represented the face-centered cubic configuration of AgNp’s. The exhibited peak indicates nanocrystalline-structured silver particles. The average particle size of bio-synthesized NPs which was between 30 and 35 nm is confirmed by SEM. The antimicrobial activity of our synthesized Nps was tested against bacteria (Escherichia. E. coli, Pseudomonas luteola, Bacillus Subtillis) as a function of nanoparticle concentration and the test was done by Disc diffusion method and antimicrobial activity was found to be quite robust. When the outcomes were compared to the effect of antibiotics like Ciprofloxacin 5, Vancomycin 30, and Ampicillin 10, these antibiotics were shown to be less effective than nanoparticles.
