Paixao Group

Chemical Sensors Lab

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.
