Flow condition in the microfluidic channel. (a) Schematic diagram of the microfluidic channel. The channel has a width (W) of 1000 μm and a height (H) of 50 μm. Blood is supplied into the channel using a programmable syringe pump with decreasing flow rate from 1 to 0 ml/h. (b) Variations of axial velocity profile at t = 0, 30, and 60 s. An instantaneous velocity field superimposed on the corresponding flow image at t = 0 s is represented in the inset. Normalized position (y/WHalf) depicts the lateral position in the channel. (c) Temporal variation of flow rate (Q) estimated by Eq. (2). Representations, depicting a 3D analytical velocity distribution of Poiseuille flow in the rectangular channel and a calculation of Q, are inserted.
