Green Synthesis of Silver Nanoparticle Using Plant Root Extract of Croton sparsiflorus and their Antimicrobial Activity

Pallavi Joshi | Joy H | Priyank Vyas

Abstract: Silver nanoparticles have a wide range of applications in the fields of catalysis, chemical sensing, biosensing, photonics, electronics, and pharmaceuticals and in biomedicine. Plants possess a wide range of phytochemical constituents, which are responsible for their medicinal properties. These phytochemicals contribute to the capping and stabilization of the silver nanoparticles. The silver nanoparticles synthesized are found to have enhanced properties when compared to that of the extract. The reducing and stabilizing property of Croton sparsiflorus silver nanoparticles were studied and it was found that silver nanoparticles exhibited better toxic activity. Hence the silver nanoparticles obtained were characterized using UV-Vis analysis and SEM. The nano-aggregates that were synthesized by the treatment of root ethanol extract of C. sparsiflorus possessed the mean diameter of 36.51-42.49 nm, which is strong indication of formation silver nanoparticles. Since the diameter of silver nanoparticles revealed by scanning electron micrograph (36.51 - 42.49 nm) lie in the considerable range for nanoparticle (0-100 nm). Applications of such eco-friendly nanoparticles in bactericidal and other medical applications, makes this method potentially exciting for the large-scale synthesis of other inorganic materials (nanomaterials).

Keywords: Silver nanoparticles, green synthesis, toxic activity, UV-VIS and SEM
