“…Besides, gel formation could be attained even at 5 °C, indicating the low-temperature adaptability of this dynamic catalysis system. 228 Moreover, the dynamic quinone-catechol redox system has been deployed to continuously generate catechol groups which endow the hydrogel with long-lasting and repeatable adhesive properties (Fig. 8b).…”

“…[23,26,27] MPNs, as amorphous networks, could be fabricated into various forms such as nanoparticles, hollow capsules, and hydrogels, and could be used as surface coating agents due to the high affinity providing by phenolic hydroxyl groups. [28][29][30][31][32][33][34][35] The coordinated self-assembly between phenolic ligands and metal ions exploiting the unique properties of polyphenols and metal ions has a wide range of applications in the biomedical fields. [36,37] For example, epigallocatechin gallate (EGCG) and Mg 2+ have been used to form composite coatings in situ on orthopedic titanium implants to enhance the osseointegration at the bone-implant interface.…”

“…[ 38 ] The tetracycline hydrochloride loade poly(acrylic acid) (PAA) hydrogel/composite formed by the polymerization of acrylic acid initiated by the self‐catalytic Fe 3+ /TA‐cellulose nanofibers exhibited ultrashort gel time (≈30s) and favorable antibacterial ability, thus are promising to be applied in a wide range of biomedical fields. [ 31 ] A MPN coordination gel based on natural low‐cost tannic acid (TA) and Ti 4+ exhibited good in situ gelation property and the ability to bind other metal ions. Five metal ions, including Fe 3+ , Cu 2+ , Zn 2+ , Co 2+ , and Ni 2+ , were always incorporated into MPN systems to develop smart gel dressings for the treatment of infected wounds.…”

Due to the abuse of antibiotics and the emergence of multidrug resistant microorganisms, medical devices, and related biomaterials are at high risk of microbial infection during use, placing a heavy burden on patients and healthcare systems. Metal-phenolic networks (MPNs), an emerging organic-inorganic hybrid network system developed gradually in recent years, have exhibited excellent multifunctional properties such as anti-inflammatory, antioxidant, and antibacterial properties by making use of the coordination between phenolic ligands and metal ions. Further, MPNs have received widespread attention in antimicrobial infections due to their facile synthesis process, excellent biocompatibility, and excellent antimicrobial properties brought about by polyphenols and metal ions. In this review, different categories of biomaterials based on MPNs (nanoparticles, coatings, capsules, hydrogels) and their fabrication strategies are summarized, and recent research advances in their antimicrobial applications in biomedical fields (e.g., skin repair, bone regeneration, medical devices, etc.) are highlighted.

“…The reason for the adhesiveness of hydrogels is the continuous formation of catechin groups as a result of a dynamic redox system [ 130 ]. The Fe 3+ /TA-CN system triggers a dynamic redox system of catechin groups; the activated potassium persulfate initiator forms a large amount of free radicals for accelerated polymerization, even at low temperatures [ 131 , 132 ] ( Figure 12 ). The author confirmed the preservation of the adhesiveness of the material during storage under extreme conditions for a long time.…”

A large number of different skin diseases such as hits, acute, and chronic wounds dictate the search for alternative and effective treatment options. The wound healing process requires a complex approach, the key step of which is the choice of a dressing with controlled properties. Hydrogel-based scaffolds can serve as a unique class of wound dressings. Presented on the commercial market, hydrogel wound dressings are not found among proposals for specific cases and have a number of disadvantages—toxicity, allergenicity, and mechanical instability. Bilayer dressings are attracting great attention, which can be combined with multifunctional properties, high criteria for an ideal wound dressing (antimicrobial properties, adhesion and hemostasis, anti-inflammatory and antioxidant effects), drug delivery, self-healing, stimulus manifestation, and conductivity, depending on the preparation and purpose. In addition, advances in stem cell biology and biomaterials have enabled the design of hydrogel materials for skin tissue engineering. To improve the heterogeneity of the cell environment, it is possible to use two-layer functional gradient hydrogels. This review summarizes the methods and application advantages of bilayer dressings in wound treatment and skin tissue regeneration. Bilayered hydrogels based on natural as well as synthetic polymers are presented. The results of the in vitro and in vivo experiments and drug release are also discussed.
