Summary: There is no previous research on sealing treatments for PEO-coated Mg with different cations in phosphate solutions. This study found that sealing PEO coatings with solutions containing Ca2+ and Mn2+ resulted in the best corrosion resistance due to the formation of dense deposition layers that seal micropores and resist erosion. The experimental establishment of a physical model and chemical equation allows for predicting the sealing effects of different cations in phosphate solutions. This research provides better guidance for formulating sealing methods for PEO coatings compared to previous studies primarily focused on the effect of phosphate-based sealing treatments.

Summary: The study successfully improved the corrosion resistance and biocompatibility of magnesium and its alloys by forming a composite coating using PEO and LDH technologies. In vitro experiments showed that the LDH-12h composite coating released fewer magnesium ions in phosphate-buffered saline and had a smaller impact on pH changes. In vivo experiments demonstrated that the LDH-12h group exhibited the best performance in enhancing corrosion resistance and tissue compatibility.

Summary: The development of bio-safe and functional Mg-Fe LDH-modified PEO coatings for the protection of magnesium-based biomedical implants is a hot topic. In this study, Mg-Fe LDH films with different Fe contents were successfully fabricated on PEO coatings using a novel two-step method. The highly-oriented LDH nano-sheets improved the anti-corrosion performance, cell adhesion and proliferation, and photothermal conversion property of the coatings. The in vitro and in vivo experiments demonstrated the excellent anti-corrosion property and histocompatibility of the PEO/Mg-Fe LDH coatings.

Summary: Nonferric oxidant precursors can directly polymerize PEDOT-inorganic composites, but most oxidants only produce powders or porous materials due to limited solubility and unmatched oxidation potentials. This study discovers a nonferric metal salt suitable for high-standard PEDOT film fabrication techniques. By adding an Fe(III) salt to stabilize the reaction and adjust the oxidant ratio, antibacterial S-PEDOT-Ag quantum dot composite films with tunable Ag wt% can be synthesized in one step.

The modified alloy exhibited enhanced corrosion resistance and sustained release of celastrol. It selectively inhibited the proliferation and migration of bone tumor cells without significant influence on normal cells. Mechanistic studies revealed that the celastrol-loaded Mg alloy induced apoptosis in bone tumor cells by upregulating reactive oxygen species (ROS) generation and causing mitochondrial dysfunction.
