Disposable silicon-glass microfluidic devices: precise, robust and cheap

摘要: Si-glass microfluidics have long provided unprecedented precision, robustness and optical clarity. However, chip fabrication is costly (∼500 USD per chip) in practice, devices are not heavily reused. We present a method to reduce the cost-per-chip by two orders of magnitude (∼5 chip), rendering disposable for many applications. The strategy based on reducing area whole-chip manifolding that achieves reliable high-pressure high-temperature fluid connectivity. resulting system was validated at 130 bar 95 °C demonstrated both energy carbon capture studied heavy oil flooding with brine, polymer, surfactant polymer solutions found as most effective solution which recovered ∼80% least amount injection while maintaining relatively uniform displacement front. In application, we measured dilation an emerging ionic liquid analog, choline chloride urea, gaseous supercritical CO2. Previously restricted niche microfluidic applications, approach here brings established benefits broad range
