Thiolated gelatin
WebGelatin (Gel) was chosen because it is an extracellular matrix (ECM)-derived protein existing abundantly in skin tissues. Thiolated gelatin (SH-Gel) was synthesized by modifying the amino group with Traut's reagent. 11 The degree of thiolation was determined to be 10 mM g −1 using Ellman's reagent. CuS 2 NPs were hydrothermally synthesized according to … WebGelatin is considered an important contributor in delivery systems because it has a low cost of production and can be easily modified. For example, a thiolated gelatin (tGel) nanoparticle was designed by chemically cross-linking to a polymerized siRNA (poly-siRNA) [64]. This demonstrates that gelatin can be easily modified.

WebChemically defined hydrogels are increasingly utilized to define the effects of extracellular matrix (ECM) components on cellular fate determination of human embryonic and induced pluripotent stem cell (hESC and hiPSCs). In particular, hydrogels cross-linked by orthogonal click chemistry, including thiol-norbornene photopolymerization and inverse electron … WebThe initial step involved the amination of native gelatin via an amine to carboxylic acid coupling reaction with ethylene diamine, followed by thiolation with Traut's reagent. The resulting thiolated product showed an increase in thiol content of up to 10-fold in comparison with control gelatin samples.
