Abstract
An electrochemical sensor comprising a counter electrode, optionally a reference electrode, and an array of multiple working electrodes, wherein at least one of the working electrodes is a film-coated electrode, and wherein the film-forming material has repeat unit that comprises six-membered non-aromatic ring. A device for electrochemical detection that comprises the sensor (an electrochemical tongue) and a method for detecting analytes with the aid of the sensor are also disclosed.
Claims29
An electrochemical sensor comprising one counter electrode, optionally a reference electrode, and an array of multiple working electrodes, wherein the array of working electrodes comprises:
- a first subarray consisting of one or more bare electrodes;
- a second subarray consisting of one or more film-coated electrodes;
- a third subarray consisting of one or more conductive additive-incorporated film-coated electrodes;
- wherein a film-forming material has a repeat unit that comprises a six-membered non-aromatic ring such that the film coated electrodes are partially selective and can cross-react with multiple redox molecules.
A device for electrochemical detection, comprising:
- one counter electrode, optionally a reference electrode, and an array of multiple working electrodes, wherein at least one of the working electrodes is a first film-coated electrode, with a film-forming material that has a repeat unit that comprises a six-membered non-aromatic ring,
- wherein the array of working electrodes further comprises at least one bare electrode and/or at least one second film-coated electrode that is different from the first film-coated electrode, wherein each film coated electrode is partially selective and can cross-react with multiple redox molecules;
- a potentiostat or galvanostat to which the electrodes are electrically connected to allow control of the potential or current of the working electrodes, respectively, to create a data set of electrochemical signals when the electrodes are immersed in a sample;
- and
- a processor configured to analyze the data set of electrochemical signals by one or more chemometric techniques.
