Abstract : The present study reports an eco-friendly and rapid method for the synthesis of core-shell nanoclusters using the modified reverse micelle method. It is a green synthetic method which uses Sesbania grandiflora Linn extract which acts as a reducing and capping agent. It is observed that this method is very fast and convenient and the nanoclusters are formed with 5-10 min of the reaction time without using harsh conditions. The core-shell nanoclusters so prepared were characterised using UV-Vis spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. Further, their effective antibacterial activity towards the gram-positive bacteria Staphylococcus aureus was found to be due to their smaller particle size.
