To take advantage of the promise of 4D materials for bioengineering applications, Alsberg and colleagues developed novel 4D materials based on gelatin-like hydrogels that change shape over time in ...

Hydrogels are often used as scaffolds in tissue engineering. Living cells infused into the material can, theoretically, grow through the gel until an entire piece of tissue forms. But to grow well, ...

Researchers have developed a hydrogel composed of poly(N-acryloylglycinamide) (PNAGAm) grafted with arginine (R)–glycine (G)–aspartic acid (D)–serine (S) peptide whose elastic modulus can be changed ...
