Consortium principal investigators :

The research team at IMT specializes in the micro- and nanofabrication of electronic devices and structures. They have successfully fabricated arrays of gold nanostructures on silicon for Surface Enhanced Raman Spectroscopy (SERS) applications.

The research team at INCDFM possesses expertise in the material characterization techniques essential for sensor development. They have a strong track record in SERS and nanoimprint lithography (NIL).

The IChF team is experienced in complex signal processing. They developed a machine learning algorithm based on evolutionary computation and information theory for problem classification. This approach required processing discretized chemical signals that resemble Raman spectra.

The DCU team has been engaged in various water monitoring projects, focusing on priority substance detection in effluents, passive sampling to screen for emerging chemicals, and trend monitoring. DCU has extensive experience in researching emerging contaminants using state-of-the-art techniques such as liquid chromatography (LC) and gas chromatography-mass spectrometry (GC-MS), along with passive sampling and chemometrics.

The DTU team has investigated pesticides in groundwater and removal technologies for drinking water. They have also quantified and modeled contamination of surface waters caused by combined sewer overflow during rainwater events.
