AC1. electrochemical sensor with a hydrophobic ring
Electrochemical sensor type AC1. with a hydrophobic ring – a hydrophobic layer is printed around the working electrode of the sensor (with a diameter of 1 or 2 mm), which ensures that the liquid applied to the working electrode of the sensor forms a drop and does not move outside to the reference and auxiliary electrodes (see the photograph below).
Such modification of the sensor is suitable, for example, before the next intended modification of only the working electrode of the sensor by the customer – for example, immobilization of a bioactive substance.
