Janus membrane holds paramount significance across diverse domains, such as chemical reactions, microfluidics, multiphase separation, and purification. Herein, we propose a new for programmable control of three-phase contact lines (TPCLs) droplets during the positive transportation process. Unlike predictable transport mode on conventional membranes (namely, TPCLs remain essentially unchanged), with engineering wettability dots (JM-EWDs) can to move along predetermined trajectories. This is attributed synergistic effect longitudinal transverse gradients at dot. More importantly, inspired by this unique structure, simple method preparing membranes. Finally, demonstrate applications JM-EWDs in emerging fields blood type testing information encryption. We believe that our work further promote development provide insights droplet TPCLs, enriching theory unidirectional liquid transport.
