Résumé : |
An American manufacturer and an invention team from Canada have developed and patented a formulation that can permanently protect plastic surfaces and metals from microbes. The technical active destroys the cell membrane of the germs without allowing them to adapt. It is applied in an online process after extrusion or thermoforming and then cured thermally or using UV light. |

- A novel mechanism for the killing of microbes
- Efficacy, biocompatibility and regulatory aspects
- Summary and outlook : reducing risks
- Fig.1 : Leaching chemicals - zone of inhibition : biocidals tend to leach in the neighbourhood of application where sublethal levels of the chemical can lead to the development of resistant microbes
- Fig. 2 : Contact killing by the phospholipid sponge effect : 1) On bottom left caption, the schematic shows the attraction of bacteria to the Bioprotect coating. 2) The middle schematic shows structural phospholipids starting to be removed from the bacterial membrane towards the coating. 3) On the right side, the schematic depicts physical destruction of the bacterial membrane leading to tell death
