Aims:
Fibre membranes containing metals have attracted great attention because of their high antibacterial efficiency. However, comparison of antibacterial activity of fibres with multi-metals in air samples has remained understudied.
Methods And Results:
Different ion exchanged nano-zeolite Y (IE-NZY) of Ag, Zn and Cu was studied. Polyvinylpyrrolidine/polyvinylidene fluoride nanofibres containing various IE-NZY were synthesized according to electrospinning technique. The presence of metal ions was confirmed using XRF. The morphological properties of nanofibres were characterized by SEM. Zone of inhibition was seen between 10·1 and 12 mm against Staphylococcus aureus and 11·5-14·57 for Escherichia coli. IE-NZY containing Ag, Zn and Cu had the highest antibacterial efficiency. In the air samples, there were any colonies on the media under the Ag/Cu-NZY and Zn/Cu/Ag-NZY nanofibres.
Conclusions:
The bacterial inhibition for nanofibres containing a three metal nano-zeolite Y (TM-NZY) is higher than bimetals (BM-NZY) types while for monometals nano-zeolite Y (MM-NZY), it was lower compared to the others.
Significance And Impact Of The Study:
The results indicate significant antibacterial activity of ion-exchanged NZY in air sampling.
