摘要
Adenine molecularly imprinted material was obtained. Well-defined silica gel particles of submicrometer size were coated with ultrathin polymeric layers, first with a polycationic poly(allylamine hydrochloride) layer that acted as a binder for the second outer layer of a photo-crosslinkable thymine-containing polyanion. Adenine template was adsorbed by the complementary thymine chromophores attached to the polymer and its imprints were created by photo-cross-linking of the outer polymer layer. The imprinted particles have shown the ability to recognize adenine and adenosine, an adenine-based nucleoside, whereas no imprinting effect was observed for purine.
