Single to use sensors that eliminate the electrode maintenance. Specially designed to work with microvolumes, this inexpensive miniaturized solution presents high reproducibility making them ideal for working in decentralized assays or to develop (bio)sensors in environmental, clinical or agri-food areas. The different modifications applied to the working electrode provide an enhanced active area and improve the electron-transfer properties.
pH monitoring via the detection of protons since the voltammetric oxidation peak potential can be easily correlated with the pH of the solution. Suitable for detecting two signals simultaneously allowing differential measurements of two analytes in the solution. Also,this electrochemical platform is useful for developing other (bio)sensing applications in multiple sectors and fields.
Differential pulse voltammetry between -0.9 and -0.1 V at 0.5 V s-1 is recommended as the detection technique with a
potential step of 0.004 V, a pulse potential of 0.1 V and a pulse time of 50 ms. Calibration plot is included per batch of electrodes
