“…Liu et al 40 used an ultra-thin ($110 nm) organogel layer coated on copper, iron, silicone, and aluminum surfaces and infused with silicone oil to produce slippery selfcleaning surfaces. Urata et al 41 designed infused polydimethylsiloxane (PDMS) which could spontaneously release its liquid upon environmental changes such as a temperature decrease to À15 C or humidity increase to 60% relative humidity. These polymers were prepared as a premixed liquid-polymer system which could make it an easily applicable overcoat for other materials.…”

Surface fouling and undesired adhesion are nearly ubiquitous problems in the medical field, complicating everything from surgeries to routine daily care of patients. Recently, the concept of immobilized liquid (IL) interfaces has been gaining attention as a highly versatile new approach to antifouling, with a wide variety of promising applications in medicine. Here, we review the general concepts behind IL layers and discuss the fabrication strategies on medically relevant materials developed so far. We also summarize the most important findings to date on applications of potential interest to the medical community, including the use of these surfaces as anti-thrombogenic and anti-bacterial materials, anti-adhesive textiles, high-performance coatings for optics, and as unique platforms for diagnostics. Although the full potential and pitfalls of IL layers in medicine are just beginning to be explored, we believe that this approach to anti-adhesive surfaces will prove broadly useful for medical applications in the future.

“…1(b)]; the resulting surface, dubbed a slippery omniphobic covalently attached liquid (SOCAL), is able to repel various liquids, including low-surface-tension alkanes [6][7][8]. Finally, a suitable lubricant oil can be added to the surface, which can be structured as is the case for slippery liquid-infused porous surfaces [9,10] or flat as is the case of lubricant-infused organogels [11,12] [ Fig. 1(c)]; any liquid can then easily be removed, as long as there is a stable intercalated lubricant layer [13][14][15][16].…”

“…2019, 6,1900996 PDMS organogels infused with various liquids were also used for anti-icing. [130] This surface also had antisticking properties against several viscous emulsions (mayonnaise, honey, ketchup, liquid glue, and Worcester sauce) and their dry solidifications. [128] Wang et al reported a liquid-paraffin swollen PDMS organogel presenting an ultralow ice-adhesion strength of 1.7 ± 1.2 kPa (at −30 °C).…”

Engineering surface wettability is of great importance in academic research and practical applications. The exploration of hydrogel‐based natural surfaces with superior properties has revealed new design principles of surface superwettability. Gels are composed of a cross‐linked polymer network that traps numerous solvents through weak interactions. The natural fluidity of the trapped solvents confers the liquid‐like property to gel surfaces, making them significantly different from solid surfaces. Bioinspired gel surfaces have shown promising applications in diverse fields. This work aims to summarize the fundamental understanding and emerging applications of bioinspired gel surfaces with superwettability and special adhesion. First, several typical hydrogel‐based natural surfaces with superwettability and special adhesion are briefly introduced, followed by highlighting the unique properties and design principles of gel‐based surfaces. Then, the superwettability and emerging applications of bioinspired gel surfaces, including liquid/liquid separation, antiadhesion of organisms and solids, and fabrication of thin polymer films, are presented in detail. Finally, an outlook on the future development of these novel gel surfaces is also provided.
