Fig. 5From: Zinc oxide nanoparticles conjugated with clinically-approved medicines as potential antibacterial moleculesAtomic force microscopic analysis of ZnO NPs and ZnO-BCD-NPs and drugs loaded ZnO-BCD-NPs. The AFM analysis showed that ZnO-NPs alone are pointed shaped (a) when conjugated with BCD, it becomes bigger in size (b) while after drug loading over the NPs surface, the shape as well as height of nanoconjugates was significantly increased showing the successful formation of drug-NPs conjugates (c–g)Back to article page
