Abstract The fabrication of microfluidic devices is often still a time-consuming and costly process. Here we introduce a very simple and cheap microfabrication process based on “razor writing”, also termed xurography, for the ultra-rapid prototyping of microfluidic devices. Thin poly(dimethylsiloxane) (PDMS) membranes are spin-coated on flexible plastic foil and cut into user-defined shapes with a bench-top cutter plotter. The PDMS membranes can then be assembled into desirable microdevices via plasma bonding. The plastic foil allows manipulation of exceptionally thin (30–300 μm) PDMS layers and can be readily peeled after fabrication. This versatile technique can be used to produce a wide variety of microfluidic device prototypes within just a few hours.
