Preventing clotting and infection on device surfaces
A variety of medical devices are made from silicones and polyurethanes, but these rapidly adsorb proteins, and cells, often leading to clotting and infection.
A variety of medical devices are made from silicones and polyurethanes, but these rapidly adsorb proteins, and cells, often leading to clotting and infection.
Our research is directed at developing coating technologies to prevent protein adsorption and subsequent negative events on medical devices, including reducing clotting and infection, as well as enabling pumpless flow of blood in microfluidic point-of-care devices. Towards this goal, we have developed “PEO-silane amphiphiles” as surface modifying additives (SMAs) for silicones and polyurethane devices.
