Polydopamine Coating in Trabecular Bone‐Like Scaffolds With Strontium‐Substituted Nanohydroxyapatite for Bone Tissue Engineering

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 9, March 5, 2026.
PLA and strontium‐substituted hydroxyapatite filaments were used in 3D printing to fabricate a trabecular‐inspired scaffold. The scaffold was functionalized with a polydopamine coating. Characterization revealed enhanced surface properties and mechanical performance, supporting its potential application in bone tissue engineering.
