As a fundamental feature of solid surfaces, wettability is playing an increasingly important role in our daily life. Benefitting from the inspiration of biological paradigms and the development in manufacturing technology, numerous wettability materials with elaborately designed surface topology and chemical compositions have been fabricated. Based on these advances, wettability materials have found broad technological implications in various fields ranging from academy, industry, agriculture to biomedical engineering. Among them, the practical applications of wettability materials in biomedical-related fields are receiving remarkable researches during the past decades because of the increasing attention to healthcare. In this review, the research progress of materials with specific wettability is discussed. After briefly introducing the underlying mechanisms, the fabrication strategies of artificial materials with specific wettability are described. The emphasis is put on the application progress of wettability biomaterials in biomedical engineering. The prospects for the future trend of wettability materials are also presented.

“…Transparency is also an important requirement for hydrogel dressings when doctors want to monitor the condition of wounds and place dressings on the wound area for a long time. [31][32][33][34] Figure 2a exhibits the plots of the transmittance of light in the wavelength range 400-700 nm for hydrogels with different concentrations of Ag NWs. The hydrogel's transparency could be altered by changing the concentration of Ag NWs.…”

Diabetic foot ulcer (DFU) is a common complication in patients with diabetic hyperglycemia, which leaves patients at increased high risk of morbidity, infection, nontraumatic limb amputations, and even early death. [1-5] Among various efforts to address this urgent issue, wound dressings are effective strategies to provide an optimal environment for wound repair. [6,7] Traditional wound dressings for DFU treatment typically cover rubber, electrospun nanofiber, cotton wool, natural or synthetic bandages, and gauzes. [8,9] Although these dry dressings are convenient to control the initial state of wound healing, they tend to adhere to the wound area once the absorbed blood and exudate dry out. [7] Besides, the dry dressings still suffer from limitations of maintaining a moisture environment, allowing gaseous exchange, and preventing infection. [6,7] In this context, a wound dressing that can deal with the above shortcomings would be ideal to speed up diabetic foot wounds healing and improve treatment outcomes. In recent years, hydrogels have generated tremendous interest in wound healing applications. [10-16] As water-based soft materials, hydrogels can facilitate wound healing by absorbing wound exudate, preventing wound desiccation, and isolating the wound from the environment, which makes them the best choice for wound healing. [17,18] However, the currently available hydrogel dressings still require to be changed frequently, which is a laborious process and inevitably cause reinjury of the wounds, wound infection, delayed healing time, and personal suffering. [19] To this end, on-demand dissolvable hydrogels represent a new class of emerging "smart" wound dressings that can be readily operated and painlessly removed. [19-24] Generally, this type of hydrogels can form in situ and dissolve on-demand via physical crosslinking cases and chemical crosslinking cases. The dissolution of physically crosslinked hydrogels is based on physical interactions, such as molecular entanglements and/or secondary forces (e.g., ionic, H-bonding, and hydrophobic associations). [19,20,22,23] Diabetic foot ulcers (DFU) remain a very considerable health care burden, and their treatment is difficult. Hydrogel-based wound dressings are appealing to provide an optimal environment for wound repair. However, the currently available hydrogel dressings still need surgical or mechanical debridement from the wound, causing reinjury of the newly formed tissues, wound infection, delayed healing time, and personal suffering. Additionally, to meet people's increasing demand, hydrogel wound dressings with improved performance and multifunctionality are urgently required. Here, a new multifunctional supramolecular hydrogel for on-demand dissolvable diabetic foot wound dressings is designed and constructed. Based on multihydrogen bonds between hydrophilic polymers, the resultant supramolecular hydrogels present controlled and excellent properties, such as good transparency, antibacterial ability, conductive, and self-healing properties. Thus, the sup...

“…Building on this work, several such artificial interfaces have been developed, primarily using polymeric hydrogels, electrostatic multilayers, and metal oxides. 5–14 Although these conventional underwater superoleophobic surfaces have found potential use in oil separation, the real-time monitoring of human respiration, and as anti-biofouling interfaces and efficient microfluidic devices, 15–23 their oil adhesion, and the consequent oil droplet mobility on these underwater superoleophobic surfaces (reflected as a change in the CAH or the roll-off angle), cannot be tuned while retaining their underwater superoleophobicity (OCA > 150°).…”
