TRACE
Total Raman and Electrophoresis Combined Environment
The TRACE project aims to provide a new instrumental platform for characterizing complex systems in
solution and at interfaces, for applications in materials and environmental sciences. The idea is to
develop a new coupling between MicroChip Electrophoresis (MCE) and Surface Enhanced Raman
spectroscopy (SERS), a technology scarcely described in the literature and with no commercial solution
available. This approach will enable the IdF community to meet the challenges of in situ and operando
analysis of heterogeneous, low-concentration samples. The project is based on two strategies for
integrating the SERS substrate, by surface functionalization or colloid integration, for the detection of
concentration zones or droplets generated inside a microfluidic channel, respectively. The combination
of these concepts will provide a versatile platform for the characterization of nano-objects in solution,
on going from nanoplastics and MOFs to gold nanoparticle-polyelectrolyte complexes, to only name
studies associated with this project.
