New hydrogel-based materials that can change shape in response to psychological stimuli, such as water, could be the next generation of materials used to bioengineer tissues and organs, according to a ...

While 3D bioprinting is widely used to construct complex biocompatible structures, researchers are now attempting to extend the technique into the fourth dimension. Here, 3D printed objects can be ...

Piezoelectricity in native bones has been well recognized as the key factor in bone regeneration. However, the current additive-manufactured scaffolds mainly focus on the reconstruction of bionic ...

Combining materials with different swelling ratios creates structures that transform into tubes when exposed to water. (Courtesy: Yu Bin Lee) Materials that controllably change shape over time – often ...

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 ...
