Enhanced Microfluidics PDMS Pneumatic Valve
This invention significantly improves the resistance of pneumatic valves in microfluidic arrays to >500 GΩ (an order of magnitude improvement) with fast opening and reasonable closing times as well as good stability. The result is greatly improved signal-to-noise ratio (SNR) resulting in higher analytical throughput at lower cost. Background:...
