    2. Microfluidics-device testing In this step‚ we use 10 µm polystyrene beads as a cell for testing the trapping ability of the device. The polystyrene beads were mixed with deionized water (DI water) and surfactant (Tween 20) in the ratio of 100: 1: 10 v/v/v. The fast green FCF (C37H34N2O10S3Na2) was added to the mixing solution for increased the particle visualization and then the solution was containing into a 10 ml syringe that connected to the device at an inlet.
