Antibacterial steel

Yesterday I wrote about the dangerous of evolving antibiotic resistant bacteria.  I’m convinced that globally, we won’t be able to decrease the usage of antibiotics enough to prevent the evolution of those bacteria, so instead we need to focus on technologies to fight them.  One cool one is a new metal alloy, that adds silver, nitrogen, and carbon to the surface of a stainless steel alloy.  The result is metal that helps prevent the spread of any bacteria (well, until they become resistant to that…!).  Read more here.

A similar approach uses a special coating (paint-like), applied to any surface, that kills MRSA bacteria.  It uses a special enzyme to directly target MRSA.  The applications are probably pretty limited for now, but it illustrates one way that technology will likely be used in the future to combat this problem.
