Abstract
Extensive research has been reported to improve the performance of existing antibacterial surfaces by reducing the extent of bacterial adhesion and biofilm formation. This study aimed to validate oil-impregnated slippery nanoporous anodic aluminum oxide (AAO) layers for the prevention of bacterial attachment on aluminum substrate. The oil-impregnation into the nanoporous structures of Teflon-coated hydrophobic AAO enhanced the repellency to the water with a low sliding angle as low as 2°, showing the omniphobicity, which is effective to reduce the contact of bacterial culture medium onto the surface of AAO. Bacterial attachment tests using Escherichia coli K-12 and Salmonella Typhimurium were conducted to evaluate the effect of antibacterial performance on the developed surfaces. Teflon-coated large pore AAO with oil-impregnation showed the highest bacterial reductions for both E. coli K-12 and S. Typhimurium among the treated samples. These results can lead to further optimization of nano-patterned AAO surfaces for antibacterial attachment.
