Supramolecular Threading of Peptide Hydrogel Fibrils [PDF]
ACS Biomaterials Science & Engineering, 2018 There is an increasing demand for biocompatible materials in biomedical applications. Herein, we report a modified α-helical decapeptide segment from the cardiac troponin C, which self-assembles into fibers with a secondary β-sheet structure. These fibers cross-link via a novel supramolecular threading mechanism which results in an atypical stiff ...

Slow-Release RGD-Peptide Hydrogel Monoliths [PDF]
Langmuir, 2012 We report on the formation of hydrogel monoliths formed by functionalized peptide Fmoc-RGD (Fmoc: fluorenylmethoxycarbonyl) containing the RGD cell adhesion tripeptide motif. The monolith is stable in water for nearly 40 days. The gel monoliths present a rigid porous structure consisting of a network of peptide fibers.

Enzymatic Cross-Linking of Dynamic Thiol-Norbornene Click Hydrogels [PDF]
, 2019 Enzyme-mediated in situ forming hydrogels are attractive for many biomedical applications because gelation afforded by enzymatic reactions can be readily controlled not only by tuning macromer compositions, but also by adjusting enzyme kinetics.

Hydroxyapatite-Tethered Peptide Hydrogel Promotes Osteogenesis
Gels, 2022 Hydroxyapatite (HAp) as natural bone composition is highly osteoinductive. To harvest its osteoinductivity in bone regenerative engineering, the HAp-supporting hydrogel is urgently needed to minimize inhomogeneous aggregation of HAp. Here, we developed a HAp-stabilizing hydrogel based on peptide self-assembly. FmocFFRR was efficient for HAp-capping due
