A self-disinfecting plastics film where bacteria invoke and dispense the disinfectant effect A self-disinfecting plastics film coated with silver and calcium phosphate has been developed by a research group led by Wendelin Stark, Assistant Professor at the Institute for Chemical and Bioengineering of ETH Zurich.
The bacteria are protected because antibiotics, the immune system and natural antibiotics can’t get to them. Lyme disease is a classic example of this. When the Lyme bacteria sense a negative living condition, or outright attack against them, they will start to build a biofilm shield. They collect materials in the body to build sort of mucus
Films containing 0.5% nitrite effectively improved redness and corresponded to 0.06 ppm residual nitrite and 75 ppm nitrosomyoglobin in packaged pork.
