摘要：

Hybrid silica films containing cation-exchange polyelectrolytes were designed and used to modify a glassy carbon electrode (GCE) for voltammetric determination of purine bases. Hybrid silica-polyelectrolyte films synthesised in the presence of adenine as structure directed component have demonstrated enhanced sorption capacity to purine base. The anodic peaks of adenine and guanine at a hybrid film-modified GCE were observed at +1.55 and +1.1V, respectively, in phosphate buffer solution at pH3.5. Oxidation currents of adenine and guanine were proportional to their concentration in the range of 0.02-0.50mM, with a detection limit of 0.015mM. The developed method was used to determine adenine in adenosine triphosphate and purine bases in hydrolyzed solutions of DNA and demonstrated good metrological characteristics.
