Water-Activated Self-Sterilizing Polymer

Sep-23-19 A self-sterilizing polymer able to kill a wide range of bacteria and viruses could help reduce the spread of hospital-acquired infections.

The material was developed by a team from North Carolina State University, who chemically modified the polymer TESET to create a sulfonic acid linked to its surface. Adding a small amount of water to the sulfonic acid surface will trigger a sudden drop in pH—killing any microbes on the material. The potency of the material can be tuned, and it remains highly effective even after repeated uses.
