Abstract

With the increasing incidence of bone defects in clinical practice, the demand for bone grafts or substitutes has become more urgent. Polydopamine (PDA)-coated bone tissue engineering materials offer a promising alternative in such cases. PDA coating is characterized by a solid coating formed by polymerization of dopamine under alkaline and oxygen-containing conditions, which can provide implants good hydrophilicity through the active functional groups contained in the structure. More importantly, the strong adhesion of the coating can provide an anchor between bone implant materials and drugs to achieve functional modification of the implant surface to enhance bone regeneration. In this review, the different effects of dopamine derivatives and their polymerization in current research were summarized. The mechanisms underlying the effects of PDA in promoting bone regeneration have also discussed in detail, providing a theoretical basis for the clinical application of PDA. Finally, a series of PDA-coated materials for the promotion of bone repair have been summarized and discussed. This review provides cutting-edge design ideas for PDA-based biomaterials and highlights promising treatment strategies for bone defects.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
