A new study suggests rough surfaces inspired by the bacteria-killing spikes on insect wings may be more effective at combating drug-resistant superbugs, including fungus, than previously understood.
Group leader, Distinguished Professor Elena Ivanova, said the latest findings shed light on the design of antifungal surfaces to prevent biofilm formation by dangerous, multi-drug resistant yeasts.
"This latest study suggests that it may not be entirely necessary for all surfaces to eliminate all pathogens immediately upon contact if we can show that the surfaces are causing programmed cell death in the surviving cells, meaning they die regardless," she said. Her team have spent the past decade replicating these insects' nanopillars in nanopatterns of their own, with this latest advance achieved using a technique called plasma etching to create the antibacterial and antifungal pattern in titanium.
