SYNTHESIS AND COMPARATIVE STUDY OF ZINC OXIDE NANOPARTICLES WITH AND WITHOUT CAPPING OF PECTIN AND ITS APPLICATION
Shubhangi Moharekar*, Priyanka Raskar, Ashish Wani and Sanjay Moharekar
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. [Download Article] [Download Certifiate] |
