Water testing is becoming increasingly important due to dangerous phenomena such as Harmful Algal Blooms (HABs). Commonly, the content of a water sample measured for detection, monitoring and control these events. Raman spectroscopy technique molecular characterization materials in solid, liquid or gaseous form, which makes it an attractive method analysing materials' components. However, scattering weak optical process requires accurate system detection. In our work, we present, from design fabrication, microfluidic device on fused silica adapted optimise spectrum samples when using probe. The features portable rapid on-site continuous flow measurements avoiding use large, costly complex laboratory equipment. main manufacturing used was ultrafast laser-assisted etching (ULAE). Finally, effectiveness demonstrated by comparing spectra known species cyanobacteria with those obtained other conventional substrates analysis. results demonstrate that device, under conditions, exhibited lower standard deviation signal, reduced background noise avoided signal variations caused drying static measurements.
