Flexible Films Tackle Biofouling in Medical Devices

Medical devices that come into contact with body fluids often face a problem called biofouling. This is when bacteria and other substances stick to the device, forming a layer that can cause issues like blood clots and infections. Traditional ways to stop this, like using certain polymers or coatings, aren't always effective in the long run. A new method has been discovered to make flexible films that can prevent this from happening. These films are made from poly(vinyl alcohol) and are infused with a type of oil that acts like a lubricant. The process is simple and involves linking the film's parts together and then adding the oil. Tests show that these films are really good at stopping bacteria from sticking and can delay blood clotting. They are also more flexible and stretchy than the usual films. This means they can be used in devices that need to bend or be moved around. This new approach could be a game-changer for medical devices and implants. It might help stop common problems like blood sticking to devices and bacteria forming slimy layers.
