Chitosan Nanocomposite Scaffolds Enable Controlled 4-Methoxycinnamic Acid Release to Enhance Bone Regeneration.
3D-printed polylactic acid scaffolds coated with polydopamine and loaded with CS nanoparticles encapsulating 4-methoxycinnamic acid (MCA), a hydrophobic polyphenolic compound with antioxidant and anti-inflammatory activities offer a robust platform for scaffold-based bone tissue engineering strategies.
