ABSTRACT
Zinc oxide (ZnO) nanoparticles (NPs) were synthesized from chemical
and pectin capping (green) method from zinc nitrate and zinc acetate.
In this study, pectin was extracted fresh ripened guava. Scanning
electron images demonstrated that chemically and pectin synthesized
ZnO NPs are irregular in shape and size. The antimicrobial activity of
E. coli and S. aureus showed higher zone of inhibition in pectin
capping ZnO NPs than chemically synthesized NPs. The antibacterial
activity of cotton fabric coated with pectin capping ZnO NPs against E.
coli showed zone of inhibition 3 to 4 times higher than chemically
synthesized ZnO NPs.
Keywords: pectin capping, guava, Zinc oxide nanoparticles, Staphylococcus aureus, Escherichia coli.
