abstract in English:
The adsorbents of adenosine, a potential cancer biomarker present in physiological fluids, urine in particular, were obtained and studied. The adsorbents were fabricated by coating submicron-sized silica gel particles with ultrathin layers of polymers containing thymine moieties. The thymine groups selectively adsorbed compounds containing adenine, a nucleobase complementary to thymine, via the formation of hydrogen bonds. Irradiation of the adsorbents with light selectively absorbed by thymine chromophores in the presence of adenine as a template molecule resulted in the photochemical molecular imprinting of adenine. The non-imprinted adsorbent showed preferential adenosine adsorption from a solution containing a mixture of nucleosides. The adenine-imprinted materials showed considerably higher than non-imprinted adsorbents selectivity of adenosine adsorption versus other nucleosides.
