Summary: This study focuses on the development of silk fibroin coating on biomedical magnesium alloys. The authors demonstrate that using hexafluoroisopropanol as a solvent and applying ethylene glycol diglycidyl ether for stabilization can improve the adhesion and corrosion resistance of the coating. The results show that the HFIP-based silk fibroin coating exhibits better compactness and adhesion strength compared to aqueous-based silk fibroin coating, and also demonstrates significantly enhanced corrosion resistance.

Summary: In this research, a self-assembled amorphous calcium carbonate (ACC)@curcumin (Cur) loaded polymethyltrimethoxysilane (PMTMS) coating on micro-arc oxidation (MAO) coated magnesium (Mg) alloy was proposed to overcome the issues of rapid corrosion and bacterial infection in using biodegradable Mg alloy for biomedical materials. The coating exhibited favorable corrosion resistance, dual antibacterial ability, and good biocompatibility. Cur was employed as an antibacterial agent and photosensitizer for photothermal therapy. The core of ACC significantly improved the loading of Cur and the deposition of hydroxyapatite corrosion products during degradation, thus enhancing the long-term corrosion resistance and antibacterial activity of Mg alloys.

Summary: Spin coating technique was used to deposit chitosan coatings on the surface of Mg20Zn magnesium alloy, resulting in increased corrosion resistance by forming CaSiO3 and Ca-3(PO4)(2) compounds on its surface. Corrosion rate was reduced from 3.2 mm/year to 1.2 mm/year for uncoated and coated substrates, respectively.

Summary: The study compares the electrochemical properties of [β-TCP/HA]n with different numbers of bilayers (n = 1, 10, 30, and 50) on biomedical devices. The results show that increasing the number of bilayers leads to decreased roughness, increased polarization resistance, and reduced corrosion rate. The coating with n = 50 bilayers demonstrates the best set of properties and is a suitable candidate for use as a protective coating for biocompatible devices.

Summary: The purpose of this study was to investigate the effect of Zn doped CaP coatings prepared by micro-arc oxidation method on MgCa1 alloy degradation. The results showed that the addition of Zn into CaP increased the corrosion resistance of MgCa1 alloy and enhanced the adhesion strength of the coatings. All samples exhibited cytocompatibility and the degradation rate of MgCa1 alloy in simulated body fluids (SBF) or DMEM was decreased by coating with CaP, which was further reduced by adding a small amount of Zn. The samples with CaP coatings and Zn doped CaP coating also demonstrated antibacterial efficacy against E.coli.
