Polymer coating for medical instruments kills colonies of dangerous bacteria

To create the coating, the researchers first dissolved polyurethane and the antibacterial drug auranofin.

and then mixed them and applied them to the catheter. The area of ​​the coating applied to the catheter was able to stretch by 500% without destroying it.

During laboratory tests, catheters, onwhich were coated, were placed in solutions and on glass plates in which were present the bacteria Staphylococcus aureus (MRSA) resistant to methicillin.

Over the course of 26 days, the coating gradually released auranofin, inhibiting the growth of MRSA on the catheter - this prevented the formation of bacterial colonies.

Earlier, scientists at Ohio State University createdElectrochemical dressings to help cope with long-term and open wounds. According to the developers, electric bandages work better than ordinary sterile bandages combined with antibiotics.
