Abstract
In this paper, we present a comprehensive theoretical and experimental investigation of unconventional droplets manipulations on a superhydrophobic- patterned surface microfluidic (S2M) platform. The S2M network pins the liquid-solid interface of droplets to the lithographically defined wetting boundary and establishes direct linkage between the volumetric and hydraulic measures. Diverse manipulation modes are characterized in a bi-droplet configuration, among which several unconventional droplet manipulations are first demonstrated. These include big-to-small droplet merging, droplet balancing, as well as bidirectional transporting, in addition to the classic small-to-big droplet merging. Furthermore, multi-stage programmable bidirectional pumping has been implemented on the S2M platform.
