A comparative study of tough hydrogen bonding dissipating hydrogels made with different network structures

Abstract

Hydrogels are excellent soft materials to interface with biological systems. Precise control and tunability of dissipative properties of gels are particularly interesting in tissue engineering applications. In this work, we...

Tannic acid: a versatile polyphenol for design of biomedical hydrogels

“…Hydrogels are fabricated first via different crosslinking methods and subsequently immersed in the TA solution for secondary crosslinking, which can provide hydrogels with high mechanical properties and multifunctionality such as adhesiveness and self-healing properties as well as superior biological activities compared to the untreated hydrogel. [236][237][238] A wide range of hydrogels comprising natural and synthetic polymers have been exposed to the TA solution to form hydrogel through a simple, feasible, and expeditious method. However, in this system, a hydrogel should be prepared before the treatment with TA solution.…”

Tannic acid post-treatment of enzymatically crosslinked chitosan-alginate hydrogels for biomedical applications

“…Recently, the production of DN hydrogels through immersion in TA solution has drawn great scientific interest that can provide hydrogels with superior mechanical properties and versatile functions such as adhesiveness and self-healing properties as well as biological activities compared to untreated hydrogels (X. Li et al, 2020;Narasimhan et al, 2021;Wen et al, 2020).…”

DNA‐Engineered Hydrogels with Light‐Adaptive Plasmonic Responses

“…The acrylamide group is known to be a hydrogen bond acceptor, while acrylic acid is a hydrogen bond donor. [67,68] Photopolymerization of AM and AA leads to the formation of the polymer phase stabilized by hydrogen bonding interactions between amide and carboxylic acid groups. Furthermore, AuNRs functionalized with double-stranded DNA (dsDNA) were introduced as multi-valent crosslinkers (Figure 1).…”
