Porfessor Stark

Wendelin Stark, a chemical engineer at the Swiss Federal Institute of Technology in Zurich has developed a film coating of calcium phosphate-encapsulating silver nanoparticles that is highly effective for inhibiting the growth of E. coli.  The bacteria consume the calcium phosphate for nutrition, and then die from the silver portion-recalling pre-antibiotic times when silver was more commonly used as a germicide.  Applications for food wraps and bandages are obvious.  SEE
