Title: Bio synthesis and characterization of plectranthus amboinicus derived silver nanoparticles impregnated with zeolite

Abstract

The green synthesis of silver nanoparticles (AgNPs) using plant extracts has gained significant attention due to its eco-friendly, cost-effective, and sustainable nature. The green synthesis approach not only corroborates the significance of phytochemical-assisted nanoparticle production but also aligns with sustainable nanotechnology principles. Silver possesses a remarkable physiochemical property that make it an excellent candidate for nanotechnology applications. In this study, silver nanoparticles were biosynthesized using Plectranthus amboinicus leaf extract, a medicinal plant known for its rich phytochemical composition. The bio-reduction of silver ions (Ag+) to AgNPs was unequivocally confirmed through visual observation, where a color change indicated successful synthesis. The incorporation of zeolite as a supporting matrix was further explored to enhance the stability and functionality of the synthesized nanoparticles. The synthesized AgNPs were characterized using various analytical techniques, including UV-Vis spectroscopy, Fourier-transform infrared spectroscopy (FTIR). The UV-Vis spectroscopy results exhibited the absorbance in the range of 350-400 nm. The FTIR analysis revealed the presence of C-H, C=O and O-H boss present in the sample. FESEM images provided an insight into the morphology where the average particle size was confirmed within the range of 10-50 nm. This study unequivocally highlights the potential of Plectranthus amboinicus-mediated AgNPs impregnated with zeolite as a promising nanomaterial for water disinfection, biomedical and environmental applications. The results suggest that this bio-nanocomposite can be explored further for its potential applications in antimicrobial coatings, drug delivery, and wastewater treatment. Future research should focus on optimizing synthesis parameters and exploring large-scale production to facilitate real-world applications.
