Focused X-ray beams for the study of heterogeneous samples have proven to be an essential tool for many scientific areas from materials science to soft matter, chemistry and nanotechnology. By combining X-rays with Raman spectroscopy in situ, samples can be studied at several size scales simultaneously, from molecular vibrations to structure and form factors, with high resolution in real space. By using such combined techniques within a microfluidics device, reactions can be probed at different stages as the reactants mix and flow through the device. Here we present the first use of a microfluidics device in a combined uSAXS – uRaman study. The formation and growth of silver nanoparticles, and their functionalisation with cysteamine, was monitored. The combination of such techniques and sample environments open new opportunities for studying materials at the nanoscale.
