Operation of the microfluidic chip with different dimensions and fluids. a) CO2 laser recipes used for the fabrication of the different microchannels. For the depth study, the length and width are fixed at 38 mm and ≈300 µm, respectively. For the length study, the depth and width are fixed at ≈470 and ≈300 µm, respectively. For the width study, the length and depth are fixed at 38 mm and ≈250 µm, respectively. b) Operation regions of the microfluidic chip with different dimensions and DI water. c) Operation regions of the microfluidic chip with 20% glycerol and 80% DI water. Response time of the OR Boolean function for different d) lengths, e) widths, f) depths of the microchannels. The flow rate is fixed at 300 µL min−1 in the experiments.
