“…To achieve this goal, the issues encountered for current gel surfaces, such as the biocompatibility of gels when used in medical devices, [64,65] have solutions with much higher possibilities. First, the exploration of novel natural livings with functional surfaces, especially those spending most of their lifetime in wet, rainy, or aqueous habitats, is pivotal to enable the discovery of unique mechanisms and design principles for advanced gel surfaces.…”

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.

“…As maintaining either the response temperature or the targeted pH‐value within the physiological range remains a challenge, other parameters become increasingly important, such as enzymatically mediated changes in polarity, ionic strength, biochemical gradients, or the presence of a certain metabolite . Effects of topography, chemical and physical functionality were simulated in so‐called liquid infused slippery surfaces (LISS) . Here, a surface is overlaid with a thin layer of liquid which is immiscible to the target (e.g., repelling) liquids.…”

Artificial Microbial Arenas: Materials for Observing and Manipulating Microbial Consortia

From the smallest ecological niche to global scale, communities of microbial life present a major factor in system regulation and stability. As long as laboratory studies remain restricted to single or few species assemblies, however, very little is known about the interaction patterns and exogenous factors controlling the dynamics of natural microbial communities. In combination with microfluidic technologies, progress in the manufacture of functional and stimuli-responsive materials makes artificial microbial arenas accessible. As habitats for natural or multispecies synthetic consortia, they are expected to not only enable detailed investigations, but also the training and the directed evolution of microbial communities in states of balance and disturbance, or under the effects of modulated stimuli and spontaneous response triggers. Here, a perspective on how materials research will play an essential role in generating answers to the most pertinent questions of microbial engineering is presented, and the concept of adaptive microbial arenas and possibilities for their construction from particulate microniches to 3D habitats is introduced. Materials as active and tunable components at the interface of living and nonliving matter offer exciting opportunities in this field. Beyond forming the physical horizon for microbial cultivates, they will enable dedicated intervention, training, and observation of microbial consortia.

Corrosion and surface icing severely shorten the service life of aluminum and its alloys. Herein, we synthesized wrinkled and porous, hollow, tubular SiO2 on an Al alloy, followed by fluorination with (Heptadecafluoro‐1,1,2,2‐tetradecyl) trimethoxysilane (FAS) and then infusing Krytox 100 for obtaining novel slippery liquid‐infused porous surfaces (SLIPSs). The unique structure greatly reduced the loss of lubricant due to the volatilization or subcooled condensation and thus effectively extended the life of the SLIPS. The corrosion resistance of as‐prepared SLIPS was five orders of magnitude higher than that of the bare Al alloy and did not change significantly after immersion in an NaCl solution for 93 days. The ice‐adhesion strength remained at approximately 18 kPa for the whole duration of the icing/deicing cycles. The samples exhibited a low contact angle hysteresis and superior self‐cleaning properties. In addition, we also revealed the differences in self‐cleaning and anti‐icing macroscopic phenomena of superhydrophobic surfaces (SHS) and SLIPS.
