Figure 5. Effect of TiO2 nanoparticles alone (350 μg/mL), ceftazidime (CEZ) alone (20 μg/mL), cefotaxime (CEF) alone (130 μg/mL), CEF and TiO2 nanoparticle in combination, CEZ and nanoparticle on multi-drug resistant P. aeruginosa shown as zone diameter (mm). For control 5 mm diameter shown is the well diameter.
