Potential flow theory has been well-known in fluid mechanics for over a century, and one may think there is not much left to say about it. However, in the past decade, new families of microfluidic devices have appeared, which involve flow in complex planar geometries. These advances in microfluidic technologies invite us to revisit established theory with a contemporary lens. In this talk, I show how classic tools of fluid mechanics can be exploited to model flow and diffusion in modern microfluidic systems. Using conformal maps, I build a flexible toolbox for the analytical modelling of devices of arbitrary geometry. Enabled by a strong collaboration between theory and experiments, this work informs the development and operation of a range of new microfluidic technologies. These new systems find applications in tissue staining, nanoparticle synthesis, and in micromodels of flow in porous media.
