Effect of CCM-GrZnO-NCs various formulations against M.R.S.A. biofilm (A). Effect of GrZnO-NCs against biofilm development in MRSA ATCC 43300 strain. Growth inhibition was assessed by comparing relative metabolic activity (R.M.A.) determined using X.T.T. assay; the untreated group served as control showing 100% activity. Experiments were performed in triplicates, and results are shown with mean ± S.D. (B) Crystal violet staining of M.R.S.A. biofilm and (C) S.E.M. observation of the MRSA ATCC 43300 biofilm upon exposure to GrZnO-NCs formulation.
