Flower shaped Zinc Oxide nanostructures was synthesized using a simple method without using any structure directing agents. Elemental analysis, crystalline nature, shape and size were examined using Powder X-ray Diffraction (XRD), scanning electron microscopy (SEM), High Resolution Transmission Electron Microscopy (HRTEM) and Energy Dispersive X-ray Spectroscopy (EDAX). XRD revealed the formation of hexagonal ZnO nanostructures. SEM and TEM analyses revealed the formation of crystalline ZnO flowers in which a bunch of ZnO nanorods assembled together to form a leaf like structure followed by flower shaped ZnO nanostructures. Thus synthesised ZnO nanostructures showed good antimicrobial activity towards gram-positive bacteria Staphylococcus aureus as well as gram-negative bacteria Escherichia coli with a MIC/MBC of 25 mg/L.
Graphical abstractThis is a simple method to synthesise flower shaped ZnO nanostructures. This method uses no structure directing agents. Thus obtained ZnO nanostructures showed good antimicrobial activity.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► A simple low temperature method selectively for flower shaped ZnO nanostructures. ► Only a metal precursor and a precipitating agent were used. ► No other dispersing/structure directing agents were used. ► ZnO nanostructures showed good antimicrobial activity.
