A zwitterion polymer coating for in-dwelling devices has been created by researchers at the University of California Los Angeles for the purpose of preventing microbes from creating irritating biofilms. In-dwelling catheters, such as urinary catheter, are a cause of concern for patients and the healthcare staff as their surface becomes prone to microbial growth. Because of this, catheters have to be replaced from time to time. However, this is not feasible for patients who use these medical devices on a long-term basis. Antibiotics cannot be used because microbes become drug resistant. Zwitterion polymer coating will protect the patients against microbes and superbugs.
