Abstract
A method for modifying the surface of a solid polymer wherein the polymer surface is exposed to an aqueous solution containing a two-ring heterocyclic compound that is described in more detail herein. The polymer and the two-ring heterocyclic compound are irradiated with electromagnetic radiation having a wavelength ranging from about 10 nm to about 400 nm to photochemically immobilize the two-ring heterocyclic compound to the polymer.
