In the March issue of Materials World, we write about nanotube-covered titanium that could be used as blood-repellent medical implants. This can be used as clot-resistant surgical implants, described by Dr Arun Kota as ‘the Holy Grail of the medical device industry.’
I’m reminded of a previous demonstration of tuneable superomniphobic surfaces from Kota back in 2014. Again working with titanium, the coating is able to trap certain low surface tension liquids on a variable scale. Also, it looks kinda cool.
