One of the research objectives of Ci2B is the development of biosensors as alternative analytical methods to traditional ones, for different applications in the agri-food, environmental and biomedical fields. The Ci2B has the infrastructure, experience and network of appropriate collaborations to address the development of both enzymatic biosensors (those whose bioactive component is an enzyme) and immunological (those based on antibodies), with different transduction mechanisms: electrochemistry, optics, piezoelectric , etc.
