Figure 1

Characterization of the LaPSD. (a) Schematic depicting the particle flow path. Black arrows denote particle path during main flow. Dotted arrows denote particle path during a sorting event. (b) Top view of the LaPSD design consisting of one inlet port, an interrogation region, a main outlet port, and a sorting outlet port. (c) Photograph depicting the fabricated LaPSD device, formed by bonding PDMS to glass cover slip. (d) 2D colorimetric vorticity plot of the LaPSD. The maximum vorticity during main flow (analogous to sorting flow) is 145 s−1. (e) Tortuosity of the LaPSD as defined by the arc to chord ratio is 1.49.
