A Study on Green Synthesis and Characterization of Silver Nanoparticles using Aloe Vera gel extract and Abelmoschus esculentus (Lady’s Finger) extract and Its Antibacterial activity

Abstract

Green synthesis is the synthesis of nanoparticles using biological systems and is greatly beneficial because of its non-toxicity and eco-friendly behaviour. This study focuses on the green synthesis of silver nanoparticles using Aloe vera gel extract and Abelmoschus esculentus extract and its characterization and antibacterial activity. The synthesized nanoparticles were characterized using Fourier Transform Infrared Spectroscopy (FTIR) and UV- Vis Spectroscopy. The bio-reduction of aqueous Ag+ ions by these extracts were identified by their colour change. The change in colour indicates the formation of AgNPs (Silver Nanoparticles). Silver nanoparticles showed maximum absorbance at 250nm in both Aloe vera gel extract and Abelmoschus esculentus. A peak obtained at this point confirmed the presence of AgNPs. Moreover, the synthesized silver nanoparticle showed potential antibacterial activity against the selective strains of bacteria such as Escherichia coli, Staphylococcus aureus and Streptococcus pyogenes which were studied using the well-diffusion method. This study gives a scope for its potential applications in biomedical field.
