Analysis of Thick Film Amperometrical Sensors Signal and Its Usage for Measurement and Characterization of Enzymes
Ondruch, Vít ; Kizek, René (oponent) ; Masojídek,, Jiří (oponent) ; Vrba, Radimír (vedoucí práce)
The principle of synchronous detection (SD) has been applied to biosensor measurement. SD principle achieves significant increases in the signal-to-noise ratio, limit of detection and overall measurement robustness. Application of SD in biosensor measurements improves the analysis of the response and avoids the influence of interference/noise produced by stirring, electromagnetic effects and influence of parasitic currents. SD also enables to decompose the signal to stimulation response and phenomena with long time of response and last but not least, to identify second-order phenomena in the signal. Linear statistical model was used to develop software for identification of the stimulation signal in the output current. SD was applied to the response signal of a Photosystem II complex (PSII) biosensor. PSII response to light stimulation follows first order kinetics. The inhibition kinetics of PSII has been studied. Kinetic constants of herbicide binding to PSII depend linearly on herbicide concentration and enable measurement of its concentration at low concentrations.
