Facile fabrication of self-healing, injectable and antimicrobial cationic guar gum hydrogel dressings driven by hydrogen bonds

High strength, self-healing sensitive ionogel sensor based on MXene/ionic liquid synergistic conductive network for human-motion detection

“…35 Although this single hydrogen bond energy is not sufficient to maintain the high stability of supramolecular systems. 36 However, the construction of multiple hydrogen bonds can provide polymer networks with abundant crosslinking sites, allowing the rapid recombination of broken hydrogen bonds between interfaces. The high hydrogen bond density also provides excellent mechanical properties for polymers.…”

Superior low-temperature tolerant, self-adhesive and antibacterial hydrogels for wearable sensors and communication devices

“…17 At the same time, compared with most natural polysaccharides including cellulose, chitosan and carrageenan, guar gum can quickly develop a full viscosity potential in cold water and does not need to be heated to dissolve. 18,19 Moreover, the affluent hydroxyl groups within the GG provide sufficient binding points for the formation of hydrogen bonds, thus making it an ideal material to prepare hydrogels with excellent stretchability and robustness.…”

A multifunctional hydrogel dressing with high tensile and adhesive strength for infected skin wound healing in joint regions

“…20 A selfhealing hydrogel can restore its original structure and function after fracture, reduce the number of wound dressing replacements required, and continue to protect the wound. 21 Many antimicrobial materials have been combined with hydrogel dressings to prevent wound infection. 22,23 Despite their potent antibacterial properties, the severe systemic toxicity or resistance caused by improper use of inorganic antimicrobials or antibiotics is still an issue that needs to be addressed.…”
