Screen printing technology seems to be one of the most promising technologies allowing biosensors, the analytical devices based on the use of biological mediators, to be largely on the market in the next future because of the chance of mass, low price production and high reproducibility. Amperometric or conductivity electrodes were printed on ceramic or polymeric substrates and coupled with biomediators or molecular imprinted polymers with the aim to obtain biological or chemical sensors. The procedures for obtaining porous alumina based ceramic devices allowing improved performances were studied. Some examples of enzyme based electrochemical biosensors useful in the environmental analysis are reported.
