Longevity and a contact-kill mechanism set apart an antimicrobial coating developed by BioInteractions Ltd from the panoply of technologies designed to prevent bacterial infection. The company based in Reading, UK, is touting its material and associated services at MEDTEC Europe in Stuttgart, Germany, for the first time this week.
“The Avent coating has a two-pronged approach,” explains Ajay Luthra, PhD. “It prevents protein adhesion while an active ingredient kills the bacteria.” Unlike silver and related antimicrobials, which have a finite lifetime, this material lasts for the life of the in-dwelling device, he adds. It can be applied to latex, silicone, polyurethane and PTFE. Avert also works with metals and has been used in an orthopaedic product made from a titanium alloy, says Luthra. It is currently licensed for use in catheters marketed by a major medical device manufacturer.
BioInteractions can transfer the technology to interested customers or do the coatings in house. Feasibility studies can be conducted free of charge.
MEDTEC Europe runs through 28 February at Messe Stuttgart in Stuttgart, Germany.
