Synthesis and characterisation of Ag- MgO – CO3O4 - Au nanocomposites using leaf extract of Hemidesmus indicus and calculation of antimicrobial activity. Green innovative has been employed for the creation of Ag- MgO – CO3O4 - Au nanocomposites herbal extract has been arranged which was the developed for the creation of Ag- MgO – CO3O4 - Au nanocomposites. Valuation for the separation of nanocomposites were organised using UV-Visible spectroscopy, Energy Dispersive X ray Analysis (EDAX) ,scanning electronic microscopy (SEM). Antimicrobial and antifungal activity of Ag- MgO – CO3O4 - Au nanocomposites prepared by using aqueous extracted was studied using disc distribution method. Antimicrobial activity of Ag- MgO – CO3O4 - Au nanocomposites exposed that the nanoparticles have superior and antimicrobial activity when experiments were achieved under comparable conditions.

Ag- MgO – CO3O4 - Au nanocomposites SEM, UV-Vis, EDAX, antimicrobial activity.
