In this changing world, we all are surrounded by the surmountable risk of getting injured. Amongst various risk factors, major burns are the most distressing and catastrophic. Burn wounds are not easy to heal via natural healing process and ultimately ended up with scar formation. If the degree of burn is high then the loss of tissue and its function is very common. To fasten-up the natural burn wound healing; zinc, an essential trace element is found to be very much effective. But due to its’ particle size limitation, less contact with wounded cells and tissues, and high inherent toxicity restrict its use. Needlessly, zinc is an element with dual action i.e. both antimicrobial and wound healing it is a prime choice to apply its aptitude in burn wound healing. To overcome the documented limitations zinc has converted to nanoparticle form. Zinc oxide nanoparticles, in particular, have attained ample of interest due to their unique properties and potential antimicrobial activity along with wound healing activity which makes it promising for the healing of topical burn wounds. Plant mediated green synthesis of nano-metal oxide particles is gaining a lot of significance due to its simplicity, eco-friendliness and extensive antimicrobial activity and recommended as an appealing substitute to not only physical methods but also chemical methods avoiding the use of the high rate of toxic chemicals and extreme surroundings. This study includes ZnO NPs role in burn wound healing with Phyto-mediated synthesis methods to provide evidence of their potential applications. Additionally, it provides an overview of traditional methods used for the synthesis of ZnO nanoparticles and characterization techniques to obtain information concerning the size, shape and optical properties along with toxicity and safety concern of ZnO NPs and its biomedical applications.

Abstract Zinc oxide nanoparticles (ZnONPs) were synthesized using Zinc nitrate hexahydrate as an oxidizer and Chrysopogonzizanioides (Vetiver) grass as a novel fuel. The X Ray Diffraction pattern as well as the Rietveld refinement showed a single-phase wurtzite structure. The average crystallite size and the lattice strain were estimated using Williamson-Hall plot. A very small value of lattice strain indicates that there is no strain and the crystal lattice is very stable. Thepresence of various functional groups in the plant extract and the Zinc –Oxygen bonding in the ZnONPs were confirmed by FTIR. The surface morphology was investigated using SEM and it showed nanorod like structure. The elemental mapping was carried out using EDAX. The EDAX spectrum suggests formation of ZnO nanorods along with high proportion of carbon and low proportion of Si as well as K might have resulted from the rich organic profile of Chrysopogon zizanioidesgrass extract. Within the UV- Visible Spectrum at 300 nm, the highly blue shifted strong absorption band was observed due to the strong quantum confinement effect. The band gap was observed to be 3.628 eV. The photodegradation of RB2 dye was studied over ZnONPs catalyst and it showed excellent photocatalytic activity. The catalyst was active up to five cycles without losing much of its efficiency. Further antimicrobial activity was tested against broad range of micro-organisms namely Staphylococcus aureus, Escherichia coli and much prevalent human fungal pathogen Candida albicans. The Minimum inhibitory concentration (MIC) for each micro-organism was determined using broth micro dilution assay.
