To fabricate complex microfluidic devices in a rapid manner, we have developed a novel method for simultaneous patterning of two sides of a single layer of PDMS using double-sided micromoulding. A mould surface coating containing aminosilanised poly(vinyl alcohol) (PVA) provides low-stress release of fragile polymer structures from the mould as well as inhibition of PDMS polymerisation at through-hole locations, thus enabling fabrication of membranes and 3D microfluidic networks in a single step. Alignment of the top and bottom patterns is achieved already during the moulding step using guiding structures in the mould halves, leading to a procedure with a minimum number of alignment and bonding steps needed to fabricate fragile 3D microfluidic devices.
