Control: ciprofloxacin (bacteria) and fluconazole (fungi); mean zone inhibition (mm) ± standard deviation of triplicate measurements. Ag = silver nanoparticles of specified precursor concentration using C. indica leaf extract; Ag/Ni = silver-nickel bimetallic nanoparticles of specified precursor concentration using C. indica leaf extract.
