Multicolor ultra high throughput parallel microfluidic flow cytometer

We report an ultrahigh throughput multi-color microfluidic flow cytometer with 32 detection channels and 64 sheath-flow channels. This flow cytometer is realized by integrating a high N.A. microball lens array with a 3D microfluidic device, which allows introducing cell samples into 32 sample channels, and sheath flows into 64 channel for parallel microfluidic focusing using only two inlets. A throughput of 384,000 cell/sec has been accomplished on a single device.
