Abstract

We synthesize the cobalt nanoparticles using drumstick leaf extract and cobalt chloride. We use drumstick leaf extract as both a reducing and capping agent. We synthesized the cobalt nanoparticles using an extract from drumstick leaves. We subsequently subjected these nanoparticles to analysis using advanced techniques like SEM, FTIR, UV-Vis spectroscopy, and EDX, yielding a substantial amount of valuable data. When administered in the form of nanoparticles, drumstick leaf extract has significant inhibitory effects on both gram-positive and gram-negative bacteria, such as E. coli and staphylococcus bacteria. Research is essential to understand the absorption and metabolism of vitamin B12 by cobalt. Artificial nanoparticles have a crucial role in the field of medicine, as they can serve as drug carriers or high-quality precursors.
