Abstract :
The research team is focused on the development of a chip-sized spectroscopy microsystem for the detection of gastrointestinal (GI) early cancerous lesions. The paper will briefly cover the outstanding properties of diffuse reflectance and fluorescence spectroscopy detection and the concept of cointegration of highly selective thin-films optical interference filters on silicon photodiodes, in order to meet the growing clinical demands for highly sensitive and reliable tools for the detection of early cancer in the GI tract. It will be also described some of the developments on-going by the research team.
