Antibacterial properties of silver dendrite decorated silicon nanowires
Abstract
<p>In this work, we report on the antibacterial properties of silicon nanowires (SiNWs) generated by via metal-assisted chemical etching (MACE) against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) bacteria strains. The results demonstrate that the antibacterial action can be attributed to the layer of silver (Ag) dendrites found on the surface of the SiNWs as a natural by-product of the MACE reaction, thus eliminating the need for a second surface modification step with an antibacterial agent. Furthermore, a 100 fold increase in bacterial adherence to SiNWs by virtue of their unique morphology is also demonstrated compared to flat silicon. We observed negligible toxicity exhibited by the SiNWs towards mammalian cells, in addition to very low rates of attachment of the mammalian cells to the SiNWs. This combination of characteristics makes these nanowire substrates an interesting alternative to other biomaterials for use in medical implants and wound dressings to combat bacterial infections.</p>
