Supramolecular biomaterials can recapitulate the structural and functional facets of the native extracellular matrix and react to biochemical cues, leveraging the unique attributes of noncovalent interactions, including reversibility and tunability. However, the low mechanical properties of supramolecular biomaterials can restrict their utilization in specific applications. Combining the advantages of supramolecular polymers with covalent polymers can lead to the fabrication of tailor-made biomaterials with enhanced mechanical properties/degradability. Herein, we demonstrate a synergistic coassembled self-healing gel as a multifunctional supramolecular material. As the supramolecular polymer component, we chose folic acid (vitamin B9), an important biomolecule that forms a gel comprising one-dimensional (1D)…

Decellularized extracellular matrices (ECMs) are being extensively used for tissue engineering purposes and detergents are predominantly used for this. A facile detergent-free decellularization method is developed for dermal matrix and compared it with the most used detergent-based decellularization methods. An optimized, single-step, cost-effective Hypotonic/Hypertonic (H/H) Sodium Chloride (NaCl) solutions-based method is employed to decellularize goat skin that resulted in much higher yield than other methods. The ECM composition, mechanical property, and cytocompatibility are evaluated and compared with other decellularization methods. Furthermore, this H/H-treated decellularized dermal ECM (ddECM) exhibits a residual DNA content of <50 ng mg−1 of dry tissue. Moreover, 85.64 ± 3.01% of glycosaminoglycans…
