Table 1.

Quantitative measurements of particle focusing behavior as a function of flow rate Q and RBC volume fraction f_RBC. For a given Q and f_RBC, the particle Reynolds number R_p, the mean in-focus lateral distance z_m from the channel centerline, the bandwidth efficiency β_z, and the focusing utility Φ_y were calculated for polystyrene beads, white blood cells, and PC-3 prostate cancer cells
