Abstract
A single-step method for applying a coating to a polymeric substrate comprising: exposing a photoreactive compound and a polymeric compound in an aqueous solvent to ultraviolet radiation in the presence of the polymeric substrate to obtain a covalently bound coating thereon comprising a reaction product of the photoreactive compound and the polymeric compound. More particularly, a method of applying a coating to a polymeric substrate in order to reduce the adsorption of analytes in solution to the substrate by imparting properties to the substrate similar to the properties of the coating applied.
