April 2004, Sensia spun-off from the technologies developed at the Biosensor Group within the National Microelectronics Centre (CNM) of the Spanish National Research Council (CSIC). Concluding research results and availability of biosensing systems already working at lab level originated the proposal of bringing them into commercialisation, after an initial phase of prototyping and industrialisation. This first idea was supported by Genetrix a young biotech company which is interested in developing biosensors for the characterisation and detection of molecular interactions which are relevant in human pathologies. Dr. Pedro Banda, with experience in the semiconductor industry and biosensor technologies, joined in to get in charge of the project.
