Surface Biofunctionalization

Related Material: links

A biosensor is an analytical device whose detection ability is based on biological interactions. It consists of a biological recognition element (enzymes, antibodies, micro-organisms, DNA, etc.) or a biomimetic recognition element attached to a physico-chemical (electrochemical, optical, thermal, piezoelectrical, etc.) transducer that converts the biological signal produced by the interaction between the recognition element and the analyte into an electric signal. This type of sensor is characterised by its specificity and extreme sensitivity.

Within the biosensor field, CETEMMSA works on both the printing and immobilisation of the biomolecules responsible for the molecular recognition and the development of transducers.
