Abstract
Methods for making modified surfaces and in particular, surfaces that may be lubricious and may be further treated to be anti-microbial are disclosed. Devices comprising modified surfaces prepared by the methods are also disclosed. An exemplary method comprises incubating a photo-initiator-coated substrate in an aqueous monomer solution that is capable of free radical polymerization, exposing the incubating substrate to ultraviolet (UV) light creating a modified surface on the substrate. An anti-microbial agent may be added to the modified surface.
