Paper Abstract

Microfluidic cytometry has led to great progress in the field of single cell analysis. Here a light scattering microfluidic cytometer with dual-channel three-dimensional (3D) hydrodynamic focusing is developed, which potentially enables single cell or particle measurements with high-throughput. The light sheet illumination is introduced to provide a uniform excitation. Two dimensional (2D) light scattering patterns of label-free single cells or particles are imaged by a CMOS sensor via an objective lens (10x). The focusing effect of our dual-channel 3D hydrodynamic focusing unit is visualized. Simultaneous measurements of standard beads with different concentrations and sizes are performed. Our results demonstrate that the light scattering microfluidic cytometer with dual-channel 3D hydrodynamic focusing is promising for parallel, label free analysis of various cells with an enhanced throughput.
