General description
Due to its biodegradablity and biocompatibility, gelatin is routinely used in hydrogels for biomedical applications such as drug delivery, tissue engineering, and 3D bioprinting. Gelatin-based hydrogels are synthesized by the crosslinking of functionalized gelatins. Depending on the identity of the functional groups, several different processes can be used to synthesize crosslinked gelatin hydrogels, including radical-based (either thermal or photochemical) and click chemistry methods. Azide-functionalized gelatin can be used in the synthesis of hydrogels using click chemistry with alkyne-containing substrates.

This paper describes the generation of "click-crosslinkable" and "photodegaradable" gelatin hydrogels from the reaction between dibenzocycloctyl-terminated photoclevable tetra-arm polyethylene glycol and azide-modified gelatin. The hydrogels were formed in 30 min through the click-crosslinking reaction. The micropatterned features in the hydrogels were

Injectable gelatin hydrogels formed with bioorthogonal click chemistry (ClickGel) are cell-responsive ECM mimics for in vitro and in vivo biomaterials applications. Gelatin polymers with pendant norbornene (GelN) or tetrazine (GelT) groups can quickly and spontaneously crosslink upon mixing, allowing for

In this study, we present a method for the fabrication of in situ forming gelatin and poly(ethylene glycol)-based hydrogels utilizing bioorthogonal, strain-promoted alkyne-azide cycloaddition as the cross-linking reaction. By incorporating nitrobenzyl moieties within the network structure, these hydrogels can be
