| titleOfInvention |
Temperature controlled valves for paper-based microfluidic systems |
| abstract |
The present invention relates to a low-cost, thermally reversible valve for paper-fluidic diagnostic devices. In particular, this invention demonstrates a tunable valve mechanism fabricated by wax-ink printing and localized heating via thin-film resistors to sequentially release liquids through a cellulose or nitrocellulose membrane. The wax-ink valve can obstruct fluid flow for a sustained time and are thermally actuated to release a controlled amount of liquid past the valve. This integrated paper-fluidic diagnostic assay device requires minimal user involvement, can be easily manufactured and tuned to meet various fluid delivery timing and incubation needs. |
