Purpose of the Study:
- To review recent advancements in hydrogel design for mechanobiology research.
- To highlight the role of dimensionality (2D to 3D) and tunable properties in dissecting cellular behavior.
- To discuss the clinical and research potential of engineered hydrogels.
Main Methods:
- Review of hydrogel systems with varying dimensionality (2D, 3D, 2.5D, sandwich).
- Focus on alginate and gelatin methacrylamide (GelMA) hydrogels.
- Discussion of fabrication techniques: photopolymerization, dual cross-linking, microfabrication.
Main Results:
- Engineered hydrogels dynamically modulate stiffness, viscoelasticity, and confinement.
