Ubc Team Finds Silver Sphere To Keep Medical Devices Free Of Bacteria

The team from UBC has developed a silver-based coating that can be easily applied to devices such as catheters and stents. The unique chemical makeup of the product solves the many challenges of the medical use of silver. “This is an extremely effective coating that will not damage human tissues and could potentially eliminate implant-related infections,” Dr. Jayachandran Kizhakkedathu, a professor of pathology and laboratory medicine, said in a statement Wednesday. “It could be very economical and it could also be applied to many different products.” 5:23 UBC biochemist recognized for role in COVID-19 vaccine development UBC biochemist recognized for role in COVID-19 vaccine development – April 8, 2022 The main challenge with using silver in medical devices is its toxicity. Although it is great for killing bacteria, too much poison can also be bad for human cells and tissues. Other problems with previous silver products include a lack of durable or adhesive properties.

“Other silver-based coatings are based on contact killing, which means that bacteria must adhere to the material to be exposed to the silver and die.” “This results in the accumulation of dead bacteria on the surface over time and making the device ineffective,” said Dr. Dirk Lange, Associate Professor of Urology, in a statement with other team members. “We prevent it by keeping the bacteria away from the surface first and then killing them by releasing silver. “As long as we prevent the adhesion of both living and dead bacteria, this coating has significant potential to maintain a clean surface for any device or material for a long time, something we have not seen so far.” The innovative “silver bullet” can be applied in a variety of ways, including spraying, and lasts longer than other previously developed coatings.
