Řešení se týká systému pro převod elektrochemického signálu na vizuální vjem zejména pro účely (bio)analytických aplikací pro stanovení látek.
In English
A simple device for the transduction of an electrochemical signal to a visual readout suitable for point ofcare diagnostics has been designed. The transducer consists of an electrochemical cell and a 4-electroniccomponents circuit, namely two resistors, one transistor and one light emitting diode (LED). The responsefrom the electrochemical cell is amplified by the transistor providing output for the direct visual readoutwith the naked eye. Function of the device was verified in the experiments with hydrogen peroxide. Sim-ple adjustment of the values of resistors provided tuneable sensitivity, positive threshold level and limitof detection as well. The biosensing abilities of the proposed system were tested on the analytical modelusing immobilised glucose oxidase. The principal benefits of the proposed platform include uniquely lowconstruction costs and high simplicity. This approach is innovative in the transduction/conversion of thesignal to visual perception and also in the signal generation – no potentiostat nor galvanostat are usedcompared to the majority of electrochemical measurements.
