In an automatic serial-parallel step all fluid segments are transferred individually to silver/polyacrylamide composite SERS spots. This approach for SERS analytics allows simple integration into segmented flow processes und provides reproducible measurements for fast screening applications. A label free screening of the deamination reaction of adenine to hypoxanthine with sodium nitrite was analyzed using the described approach.enSurface Enhanced Raman SpectroscopySegmented flowAnalyticsMicrofluidic screeningconference paper
