Effect of drying method on mechanical, thermal and water absorption properties of enzymatically crosslinked gelatin hydrogels.
Enzymatically crossliked gelatin hydrogel was submitted to two different drying methods: air drying and freeze drying. The resulting polymeric tridimensional arrangement (compact or porous, respectively) led to different thermal and swelling properties. Significant differences (p < 0.05) on thermal and mechanical characteristics as well as swelling in non-enzymatic gastric and intestinal simula...
متن کاملReversible Ag(+)-crosslinked DNA hydrogels.
DNA hydrogels, consisting of Y-shaped nucleic acid subunits or of nucleic acid-functionalized acrylamide chains, undergo switchable gel-to-solution transitions. The Ag(+)-stimulated formation of cytosine-Ag(+)-cytosine complexes results in the crosslinking of the units to yield the hydrogels, while the cysteamine-induced elimination of the Ag(+) ions dissociates the hydrogels into a solution ph...
متن کاملClick-Crosslinked Injectable Gelatin Hydrogels.
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 high viability of encapsulated cells, establishment of 3D elongated cell morphologies, and ...
متن کاملEnzymatically-stable oxetane-based dipeptide hydrogels.
Low molecular weight gelators that are not easily degraded by enzymes have a range of potential applications. Here, we report new Fmoc-protected dipeptides in which the amide carbonyl group has been replaced by an oxetane ring. Remarkably one of these peptidomimetics, but not the corresponding dipeptide, is an effective gelator, forming hydrogels at a concentration of 3 mg mL-1. On assembly, th...
متن کاملModular Hydrogels for Drug Delivery
The development of novel drug delivery systems is an essential step toward controlled site-specific administration of therapeutics within the body. It is desirable for delivery vehicles to be introduced into the body through minimally invasive means and, these vehicles should be capable of releasing drug to their intended location at a controlled rate. Furthermore, it is desirable to develop dr...
