Surface wetting gradients are desirable due to their ability to passively transport liquid
droplets without the aid of gravity. Such surfaces can be prepared through topographical or …

Here, a smart fluid‐controlled surface is designed, via the rational integration of the unique
properties of three natural examples, ie, the unidirectional wetting behaviors of butterfly's …

Directional liquid transport has broad engineering applications, and recent efforts have
demonstrated the feasibility of rapid and long-distance directional transport using external …

A superhydrophilic surface decorated with 2D hydrophobic water barriers is proven to be a
potential platform for unidirectional liquid transport. Differing from the existing systems based …

This work demonstrates a novel technique for fabricating surfaces with roughness and
wettability gradients and their subsequent applications for chemical sensors. Surface …

We demonstrate the label-free and selective detection of interleukin-6 (IL-6), a key cell-
signaling molecule in biology and medicine, by integrating an OECT with an immuno-affinity …

Under-water and unidirectional air penetration, viz. air “diode”, was effectively achieved on
the basis of a composite mesh with Janus wettability. In the aqueous solution, the air …

Highly adherent wettability patterns on the substrate-independent superhydrophobic
surfaces of trimethoxyoctadecylsilane modified titanium dioxide (TiO2)-based coatings were …

The rational manipulation of fluid behavior by functional interfaces plays an indispensable
role in the development of advanced materials and devices involving liquid/solid …

Driving a liquid droplet with control of directional motion on a solid surface, by introducing a
surface wettability gradient or external stimuli, has attracted considerable research attention …
