Mussel-inspired bioceramics with self-assembled Ca-P/polydopamine composite nanolayer: Preparation, formation mechanism, improved cellular bioactivity and osteogenic differentiation of bone marrow stromal cells

Poly(dopamine) coating of 3D printed poly(lactic acid) scaffolds for bone tissue engineering

“…c o m / l o c a t e / m s e c surfaces via self-polymerization by the oxidation of DA in a weak alkaline buffer solution [14]. The material-independent PDA coating can be easily and quickly obtained by base-triggered oxidation and polymerization of DA, and the PDA adlayer serves as a platform for post-modification, including spontaneous deposition of metal and bioceramic, as well as covalent immobilization of several serum adhesive proteins [15][16][17]. The surface hydrophilicity and bioactive functional groups were improved cell attachment and differentiation on self-assembled PDA/calcium phosphate composite nano-layer [15].…”

A novel cytocompatible, hierarchical porous Ti6Al4V scaffold with immobilized silver nanoparticles

“…The synergistic contribution of micro/nano-porous topography and adhesive chemical property of PD (increased surface hydrophilicity and bioactive functional groups (e.g. OH, NH 2 ) [18]), as illustrated in Fig. 3E, could probably compensate adverse biological effects, if any, brought by AgNPs immobilization.…”

Electroresponsive and cell-affinitive polydopamine/polypyrrole composite microcapsules with a dual-function of on-demand drug delivery and cell stimulation for electrical therapy

“…Yang et al 33 used a biomimetic approach to coat PDA on various materials and found that PDA has effectively immobilized growth factor and promoted the proliferation and differentiation of human neural stem cells on PDA composite materials. Wu et al 34 used a self-assembly method to prepare a calcium phosphate/PDA composite nanolayer on the surface of a β-tricalcium phosphate scaffold. They also reported that the addition of PDA improved the attachment, proliferation and differentiation of human BMSCs.…”
