A microfluidic cytometer for white blood cell analysis

Despite the wide use of cytometry for white blood cell classification, the performance of traditional cytometers in point‐of‐care testing remains to be improved. Microfluidic techniques have been shown with considerable potentials in the development of portable devices. Here we present a prototype of microfluidic cytometer which integrates a three‐dimensional hydrodynamic focusing system and an on‐chip optical system to count and classify white...
