Treated Silk Boasts Super Powers; Kills Bacteria of All Sorts

Luxurious texture has been the main virtue of silk, and it looks like there was much more under the hood of this gorgeous piece of clothing. Defense scientists from the US have developed a way to turn silk into a bacteria destroyer.

Some chemicals are made as a coat for silk by a simple dipping process. After the coating process, the silk can kill bacteria and even coated spores. The research results were reported this week in ACS Applied Materials & Interfaces.

The American Chemical Society (ACS) is a scientific society based in the United States that supports scientific inquiry in the field of chemistry. Application for the fabric could include curtains and protective coatings to protect homes and other buildings from a biological attack.

Previous research showed that other fabrics dipped into chemical solutions could damage bio-molecules.

Silk was chosen because it is widely available around the world, has excellent mechanical properties and offers good biocompatibility.

A chemical solution similar to household bleach was used to coat the silk. After letting it dry, the silk could kill E.coli and spores of bacteria similar to Bacillus anthracis (anthrax).

Some possible applications include the usage of prepared silk as a filter material for treating contaminated water or for cleaning air from pathogenic spores.
