Droplet manipulation with bioinspired liquid-infused surfaces: A review of recent progress and potential for integrated detection

Advances towards programmable droplet transport on solid surfaces and its applications

“…The resulting thin layer of liquid covering the surface of the porous substrate determines its properties at the interface. As discussed in depth in a recent review on the topic, 30 SLIPSs have been the subject of intensive research because of their self-healing, anti-icing, anticorrosion and anti-biofouling characteristics as well as for their excellent liquid repellency. In fact, SLIPSs are often characterised by a low contact angle hysteresis (r101), thus easing the transport of droplets made of a liquid immiscible with the infused liquid (Fig.…”

“…Beyond the use of body forces (Section 3.1), the dynamical manipulation of liquid droplets on SLIPSs has also been achieved either by using stimulus-responsive liquids for infusing the porous substrate or by using stimuli-responsive materials for fabricating it. 30…”

Gradient Wetting Transition from the Wenzel to Robust Cassie-Baxter States along Nanopillared Cicada Wing and Underlying Mechanism

“…Gradient surfaces are important for some living organisms [11] . Inspired by the aforementioned natural systems containing surface gradient or diversity that enables water condensation or transport, micro/nanostructures with gradients in surface energy or gradients in Laplace pressure have been developed [11][12][13] . Consequentially, liquid behavior manipulation by structure-inducing surface gradient has become an area of interest because of its potential applications in oil/water separation, water collection, microfluidics, self-cleaning, and liquid transportation [14][15][16] .…”

Thermo-responsive wettability via surface roughness change on polymer-coated titanate nanorod brushes toward fast and multi-directional droplet transport

“…A smart surface with stimuli-responsive wettability is of great importance for various applications including self-cleaning, oil/ water separation, water motion, droplet microuidics, biochemical analysis and drug delivery. [1][2][3][4][5] In general, such smart surfaces can be achieved by the use of responsive molecules or polymers that can reversibly switch their chemical transformation and polarity 6 by external stimuli such as light, 7 pH, 8,9 electric eld, 10 magnetic eld, 11 and temperature. 12,13 Among them, a thermo-responsive smart surface has aroused paramount interest as temperature is the most common and facile stimulus for practical applications.…”
