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. Keywords: Screen printing, enzymes, biosensors, molecular imprinting. |
