Abstract

A new method is described and used to integrate an immobilized Surface Enhanced Raman Spectroscopy (SERS) substrate in microchannels. This is based on the direct and fast electrodeposition of an adherent Ag layer on a microchannel wall. This layer exhibits a spatially uniform nanostructure allowing the enhancement of the Raman signal by an analytical factor of 2.10+4 for crystal violet molecules. The microsystem thus elaborated is used to examine the photothermal effect, induced by the laser used, on the SERS spectra under liquid flow.
