We introduce an observation chamber dedicated to image, at the nanoscale, the kinetics of reactions taking place at the liquid/solid interface. The assembly of this microfluidic cell is straightforward and, most importantly, its design allow the operator to precisely regulate the hydrodynamic flow and control the concentration in reagents at the observation window.
