Potentiometric studies of selective reactions of bioactive substances on the surface-modified tantalum electrodes.
The method of highly selective potentiometric detection of bioactive substances developed by us has been much improved by using tantalum metal as a electrode material, by employment of a new method of modification (using gamma-aminopropyltriethoxysilane and cyanogen bromide), and by the pretreatment with inert protein before the measurement. As the consequence, the response in the electrode potential shift has been increased and the reproducibility of the data reached almost 100%.
