Efficient Bioactive Surface Coatings with Calcium Minerals: Step-Wise Biomimetic Transformation of Vaterite to Carbonated Apatite

Biomimetics, Journal Year: 2024, Volume and Issue: 9(7), P. 402 - 402

Published: July 2, 2024

Carbonated apatite (CAp), known as the main mineral that makes up human bone, can be utilized in conjunction with scaffolds to increase their bioactivity. Various methods (e.g., co-precipitation, hydrothermal, and biomimetic coatings) have been used provide bioactivity by forming CAp on surfaces similar bone minerals. Among them, use of simulated body fluids (SBF) is most popular method for generating CAp, it a mimetic environment. However, coating using SBF require at least week formation. The long time takes coat point improvement field requires rapid regeneration. Here, we report step-wise form calcium carbonate vaterite (CCV) precursor. We manufacture CCV-transformed (V-CAp) surface 4 h immersing CCV phosphate solution. V-CAp deposited was analyzed scanning electron microscopy (SEM) images according type solutions optimize reaction conditions. X-ray diffraction (XRD) attenuated total reflection-Fourier transform infrared (ATR-FTIR) analysis validated conversion surfaces. In addition, proliferation differentiation osteoblasts vitro. showed 2.3-folded higher cell 1.4-fold ALP activity than glass surface. biocompatible allows environment regeneration has potential confer biomaterial surfaces, such imparting non-bioactive metal or scaffold within one day. It rapidly carbonated apatite, which greatly improve efficiency research industrial applications.

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

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 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.
