Dose-dependent enhancement of in vitro osteogenic activity on strontium-decorated polyetheretherketone

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Янв. 24, 2025

Polyetheretherketone (PEEK) is widely used in orthopedic and dental implants due to its excellent mechanical properties, chemical stability, biocompatibility. However, inherently bioinert nature makes it present weak osteogenic activity, which greatly restricts clinical adoption. Herein, strontium (Sr) incorporated onto the surface of PEEK using mussel-inspired polydopamine coating improve activity. X-ray photoelectron spectroscopy ion release assay results confirm that different concentrations Sr are substrate surfaces. The strontium-modified samples show a stable 35 days detection. Better MC3T3-E1 pre-osteoblasts adhesion, spreading, proliferation can be observed groups, demonstrates with improved compatibility. boosted activity has been demonstrated by better performed ALP extracellular matrix mineralization, collagen secretion, remarkable up-regulation ALP, OCN, OPN, Runx2, Col-I, BSP, OSX pre-osteoblasts. Additionally, exhibit dose-dependent enhancement osteoblasts compatibility PEEK-Sr10 group shows best. These findings indicate strontium-decorated promising application implants.

A mussel-inspired multiwalled carbon nanotube (MWCNT) nanocomposite (MWCNTs@CCh-PEI) was prepared by the co-deposition of catechol (CCh)/polyethyleneimine (PEI) and modification MWCNTs for efficient removal methyl orange (MO). The effects MO solution pH, contact time, initial concentration, temperature on adsorption capacity MWCNTs@CCh-PEI were investigated. results indicate that two times higher than pristine under same conditions. kinetics followed pseudo-second-order model, suggesting process chemisorption. isotherm shows experimental data fitted well with Langmuir a correlation coefficient 0.9873, indicating monolayer adsorption. theoretical maximum determined to be 400.00 mg·g
