Abstract
Characteristics of nickel amperometric transducers connected to experimental Ukrainian potentiostat and to commercial potentiostat PalmSens were studied in this work. During this, intrinsic characteristics of transducers and differences caused by connection to different potentiostats were examined. Comparison was made in several working modes. Amperometric electrodes made from nickel and biosensors for glucose determination (obtained by immobilization of glucose oxidase onto the surface of these electrodes) were connected to the potentiostats and effectiveness of measurement of hydrogen peroxide and glucose contents by both potentiostats was compared. I.e., sensor responses, signal noise, limit of detection of substances, calibration curves for determination of hydrogen peroxide and glucose, reproducibility of responses during continuous operation were compared. Also selectivity of sensors to hydrogen peroxide respectively to main interfering substances (ascorbic acid and ethanol) was checked. It was shown that nickel transducers can be a basis for creation of chemo- and biosensors. Besides, it was demonstrated that for the most parameters new Ukrainian potentiostat is not inferior to the potentiostat PalmSens and Ukrainian potentiostat can serve as a cheaper analog of PalmSens during development of biosensor test systems
