Novel multi-way microvalve with ease of fabrication and integration for microfluidics application

We present a miniaturized active multi-way microvalve, with a rotor, measuring only 3.7 mm in diameter and having a footprint of only about 14 mm2, and that is designed for integration into microfluidics chips, allowing for overall size reduction for microfluidics platforms. It has a zero dead volum...
