Abstract
A passive micromixer was prepared by photopatterning a periodic arrangement of nanoporous polymer monolith (nPPM) structures directly within the channel of a plastic microfluidic chip. By optimizing the composition of the polymerization solution and irradiation time we demonstrate the ability to fabricate nPPM in regular 100 μm segments. By monitoring laser-induced fluorescence (LIF) of reaction products we found this photopatterned array to have the highest mixing efficiency when compared to an equivalent length of continuous segment plug of nPPM and an open channel. These results indicate that the regularly spaced open areas between the plugs of nPPM enhances mixing efficiency.
