Regulating the flow of fluid in microfluidic devices enables a wide range of assay protocols for analytical applications. A programmable, paper-based microfluidic device fabricated by using a method of cutting and laminating, followed by printing, is reported. By printing silver-nanoparticle (AgNP) and poly[4,5-difluoro-2,2-bis(trifluoromethyl)-1,3-dioxole-co-tetrafluoroethylene] (PTFE) patterns on the surface of a paper channel, we were able to either increase or decrease the flow of fluid in the fabricated devices. By using hydrophilic AgNP patterns, we were able to increase the speed of fluid flow in the channel by up to 15 times compared to that in a pristine channel, and by using hydrophobic PTFE patterns, we were able to delay that speed by a factor of about 3. Using the programmable, paper-based microfluidic device, we demonstrated a single-step protocol for detecting glucose and a multi-step protocol for detecting methyl paraoxon (MPO). We anticipate that our programmable, paper-microfluidic device will lead to improved fluid handling techniques, which are crucial for achieving a wide range of analytical assays.
