The American Chemical Society said on the 23rd that scientists have discovered a simple and inexpensive method that can transform ordinary silk into silk fibers that have the ability to sterilize and kill spores. Experiments have shown that the newly obtained silk fiber can kill pathogenic bacteria in a few minutes, and even include protective spores of microbial spores, including anthrax.
Dr. Rajesh Neck, research director, said that in an unfavorable environment, Bacillus species of bacteria (including anthrax) will become dormant spores, wrap themselves in a strong protective film, and experience heat and radiation. After surviving severe external conditions such as antibiotics, spores were revived 250 million years ago.
In real life, certain chemicals (mostly oxidants including chlorides) have the ability to kill bacterial spores. People often attach these chemicals to fibers such as cotton, polyester, nylon, and Kevlar, effectively killing many bacteria. However, their effect on spores was not significant.
In the new study, scientists envision using the same chemicals on silk to see if they have better ability to kill spores. To this end, they developed chloride-containing silk fibers that were produced by soaking the silk in a solution similar to a household bleach material and then drying. The experimental results show that silk treated for only 1 hour can kill all E. coli deposited on it within 10 minutes, and it has the same effect on spores similar to anthrax.
Scientists said that given the potential for bactericidal and sporicidal capacity of chloride silk fibres, it is expected to have a wide range of uses, including the purification of water and the release of toxic substances, and people can use it to make temporary curtains and other protective clothing in the event of an anthrax terrorist attack.
