Killer Silk Makes Protective Curtains

Mar-19-12 Scientists have developed silk able to kill even extremely hardy bacteria, which could lead to a new array of protective clothing and emergency curtains.

The 'killer silk' was produced through a basic and inexpensive method, dipping basic silk into a diluted chlorine bleach solution and allowing it to dry. The silk killed almost all E. coli bacteria exposed to it within 10 minutes, and was even able to kill the  Bacillus thuringiensis spores, which are can survive extreme conditions due to its thick coating.

The silk could be used to create barrier protection during biological attacks, purify water, or as an extra step in filters.
