‘The wings of some beetles in the Sahara desert are shaped by evolution to be antibacterial,’ Professor Romoli told The Times.
‘They have nano-tubules and nanoedges that break the exterior cellular membrane of the bacteria.
‘The changes you can see on the wings of butterflies are also achieved through nano-patterns that exchange heat by convection.
‘Recently this type of architecture was applied to microprocessors to increase the heat exchange.’
A number of non-stick pans made out of Teflon already exist on the market, but once the pan is scratched, it usually needs to be replaced.
