| 摘要 |
An apparatus comprising first and second electrodes (201, 202) separated by an electrolyte (203), the first and second electrodes (201, 202) configured to exhibit a potential difference therebetween on interaction of the first electrode (201) with an analyte, wherein the first electrode (201) is configured such that its electrical conductance and electrochemical potential are dependent upon the amount of analyte present, the electrical conductance and electrochemical potential of the first electrode (201) affecting the potential difference between the first and second electrodes (201, 202), and wherein the apparatus comprises respective first and second terminals (204, 205) configured for electrical connection to a readout circuit to enable determination of the presence and/or amount of analyte based on the potential difference. |
