• Sustainable novel green synthetic strategy to synthesis zinc oxide nanocrystals
• ZnO nanocrystals using rambutan peel wastes via zinc-ellagate complex formation
• Possible mechanism of ZnO formation with rambutan peel extract has predicted
• Green perspective ligation agents usage and reutilise biological waste material
• ZnO nanocrystals employing Nephelium lappaceum L., peel is not yet predicted

In the present investigation, we report a sustainable novel green synthetic strategy to synthesis zinc oxide nanocrystals. This is the first report on sustainable biosynthesis of zinc oxide nanocrystals employing Nephelium lappaceum L., peel extract as a natural ligation agent. Green synthesis of zinc oxide nanocrystals was carried out via zinc-ellagate complex formation using rambutan peel wastes. The successful formation of zinc oxide nanocrystals was confirmed employing standard characterisation studies. A possible mechanism for the formation of ZnO nanocrystals with rambutan peel extract was also proposed. The prepared ZnO nanocrystals were coated on the cotton fabric and their antibacterial activity were analyzed. ZnO nanocrystals coated cotton showed good antibacterial activity towards Escherichia coli (E. coli), gram negative bacteria and Staphylococcus aureus (S. aureus), gram positive bacteria.
