Fig. 3: Examples of trapping liquid with a micromesh structure to trap liquid in various ways.

A Fabrication of microfluidic channel by injecting liquid into a micromesh and channel with width and height of 1 mm and a gap of 400 μm to trap liquid inside the microfluidic 3D channel, three-dimensionally twisted microfluidic channel (gap: 400 μm and 1000 μm). Liquid inlets are marked with black arrows. B Method of selectively filling liquid by increasing the pressure applied to the mesh by gradually increasing and immersed depths when it starts to fill liquid according to the micromesh gap size. Scale bar = 1 cm.
