3D-printed spines for programmable liquid topographies and micromanipulation
Single spine
Let us consider a conical spine crossing the water-air interface. Figure 1a presents a sketch of the conical spine defining its geometrical characteristics: the radius of its base R and its height H. A meniscus forms around such a…
