Abstract—Amperometric sensors can be used for many
applications, as they can be excellently manufactured in roll-toroll
printing processes. However, careful material selection is of
particular importance for high sensitivity and selectivity. For
example, the choice of the reference electrode material is critical
to ensure a stable electrical potential, and the working electrode
material needs to match the redox system used. For biosensor
applications, the immobilization of the receptor molecules via
printing technologies must be ensured, for which again the sensor
materials significantly contribute. To illustrate these challenges,
examples are presented for the detection of small molecules,
proteins and DNA.
