Design and proof-of-concept of the 3D printed microfluidic chip. (a) The 3D design of the microfluidic chip with the corresponding dimensions. (b) A schematic illustration of the principle of the dual beam optical trap system in the designed 3D printed microfluidic chip is shown. The sample solution is hydrodynamically focused and sheathed by the buffer solution. (c) An exemplar photo of the 3D printed microfluidic chip. Scale bar is 10 mm. (d) Water containing color additive is flown through the chip to simulate the sample solution. Scale bar is 4 mm. (e) Trajectory of \(10 \,\upmu \mathrm{m}\) polystyrene particles flowed through the sample channel. Scale bar is 200 µm. COMSOL simulations are presented in (f) showing the speed of the transported particles for a straight (top) and square zig–zag mixer (bottom) structure. The percent transported particles at the end of zig–zag and straight channels with the same total path length is shown in (g) as a function of time/volume.
