A Wettability Gradient Synergistic Bionic Wedge-Shaped Track for Ultrafast and Long-Distance Spontaneous Transport of Droplets

·h). Additionally, it showed effective self-transport capabilities in the transport experiment with a blood droplet, achieving a transport distance of 25 mm and an average speed of 14.2 mm/s. These results highlighted the significant potential of WGWT for applications in microfluidics, water collection, and biological detection.
