In this study we investigate the liquid sample delivery speed and the efficiency of microfluidic channels for low-cost and low-volume diagnostic devices driven only by capillary forces. We select open, non-porous surface grooves with a V-shaped cross section for modeling study and for sensor design. Our experimental data of liquid wicking in V-grooves show(More)
The mechanism of the generation and sustainability of noncoalescent droplets (NCDs) was investigated at the liquid-air interface of the same liquids in the context of inkjet printing. The Weber number (We) was used to correlate and predict the generation of NCDs in a falling-drop experiment. This study found that NCDs can be generated for We higher than(More)
