Quantitative analysis of a chemical reaction in a microfluidic device using stimulated Raman scattering microscopy — •Peter Fimpel, Martin Josef Winterhalter, and Andreas Zumbusch — Universität Konstanz

Microfluidic devices offer the possibility to monitor reactions with precise control of the reactants ratios. The laminar flow in our device allows us to visualize the reaction kinetics due to pure diffusive mixing. SRS is a perfect tool to quantitatively monitor such processes since it has chemical contrast, is free of non-resonant background and scales linearly with the chemical concentration. This enables us to measure the local concentration with submicrometer spatial resolution and fast acquisition times compared to spontaneous Raman scattering microscopy.
