(a) Schematic of the fabrication process, first the device is irradiated by focused femtosecond laser pulses and subsequently exposed to an aqueous solution of hydrofluoric acid, allowing the three-dimensional (3D) microchannel formation. (b) 3D rendering of the proposed device, which is constituted by a sequence of straight channels intercalated by tightly curving loops. Microscope images of the fabricated device from (c) top and (d) side view. Panels c and d have the same scale bar.
