Paixão Group

The Paixão group develop sensor technologies, to propose chemical sensor for clinical, environmental and forensic applications. Current research projects include the development of paper-based colorimetric and electrochemical devices for applications in the areas related previously using, or not, chemometrical approaches. Detailed information about current research projects can be found on the Research page.
