Supramolecular hydrogels pdf

Self-healing supramolecular hydrogels have emerged as a novel class of biomaterials that combines hydrogels with supramolecular chemistry to develop highly functional biomaterials with advantages including native tissue mimicry, biocompatibility, and injectability. These properties are endowed by mediated hydrogels.24 Similarly, Zhang et al. demonstrated that an inclusion complex formed from an ester derivative of thetripeptidePhe-Gly-Gly and CB[8] could be polymerised to form both supramolecular hydrogels and microgels.25,26 They noted that supramolecular hydrogels formed using this approach were significantly more mechanically To overcome this challenge, supramolecular assembly is exploited to localize hydrogels at the injection site and introduce subsequent covalent crosslinking to control final material properties. Supramolecular gels are designed through the separate pendant modifications of hyaluronic acid (HA) by the guest-host pair cyclodextrin and adamantane, enabling shear-thinning injection and high target site retention (>98%). Abstract. Supramolecular hydrogels assembled from amino acids and peptide-derived hydrogelators have shown great potential as biomimetic three-dimensional (3D) extracellular matrices because of their merits over conventional polymeric hydrogels, such as non-covalent or physical interactions, controllable self-assembly, and biocompatibility.

Definition. Supramolecular hydrogels are one of the hydrogels consisting of a solid three-dimensional network with noncovalent bonds such as hydrogen bond, hydrophobic interaction, and cation-π and π-π interactions. Although a morphology of chemical gels is stabilized by chemical cross-linker, that of supramolecular hydrogels is stabilized by the This review describes various types of supramolecular hydrogels using a repertoire of diverse building blocks, their use for protein delivery and their further application in TE contexts. By reviewing the recent literature on this topic, the merits of supramolecular hydrogels are highlighted as well as their limitations, with high expectations for new advances they will provide for TE in the Supramolecular hydrogels are one of the hydrogels consisting of a solid three-dimensional network with noncovalent bonds such as hydrogen bond, hydrophobic interaction, and cation-π and π-π interactions. Although a morphology of chemical gels is stabilized by chemical cross-linker, that of supramolecular hydrogels is stabilized by the Supramolecular hydrogels are 3D, elastic, water-swelled materials that are held together by reversible, non-covalent interactions, such as hydrogen bonds, hydrophobic, ionic, host-guest Self-assembly of supramolecular hydrogels is driven by dynamic, non-covalent interactions between molecules. Considerable research effort has been exerted to fabricate and optimise supramolecular hydrogels that display shear-thinning, self-healing, and reversibility, in order to develop materials for biomedical applications. Until now, there have been many preparation methods of zwitterionic polymer hydrogels by physical or chemical polymerization, but few reports about the
