Chemists supported by the Swiss National Science Foundation (SNSF) have developed a one-pot synthesis process to encapsulate nanoparticles. This type of particle could improve the antimicrobial coating of implants. Western populations live longer while enjoying good health. More and more people, for example young pensioners, have implants fitted to pursue their activities. But such surgery is not without its risks: during an operation, bacteria can reach the surface of the implant. Once they have colonised the surface and formed a biofilm, the implant has to be removed and the wound cleaned. No new implant can be fitted till the infection has cleared up completely. These complications affect 2% of artificial hip joints, 5-10% of artificial knee joints and reach 50% for cardiac shunt and stent operations.
