Superhydrophobic titania nanoflowers for reducing adhesion of platelets and bacteria
Thrombosis formation and bacterial infection are key challenges for blood-contacting medical devices. When blood components encounter a device's surface, proteins are adsorbed, followed by the adhesion and activation of platelets as well as an immune response. This culminates in clot formation via the trapping of red blood cells in a fibrin matrix, which can block the device's function and cause severe complications for the patient. Bacteria may also adhere to a device's surface. This can lead to the formation of a biofilm, a protective layer for bacteria that significantly increases resistance ...
