“…While for VSMC, similar trend could be detected with a little higher NO release value in each testing group, i.e. the MgZnYNd-B-A-P group also showed the highest value among all the testing groups, which was consistent with our previous data when studying the effects of MgF 2 /polydopamine coating on MgZnYNd alloy [51] . Preceding reports demonstrated NO capacity in obstructing proliferation of VSMC cell [72][73][74] and promoting endothelial cells proliferation [75] except its role in regulating vascular elasticity as a self-produced vaso-active substance.…”

“…Hence we may predict that PLGA coating after BTSE-APTES pre-treatment owns a much better potential to protect Mg from over-fast corrosion than direct PLGA coating. The conclusion that more negative E corr corresponds to a faster corrosion rate was also reported in other published studies, for example corrosion rate of pure Mg in a sulphate medium by Baril et al [50] and MgF 2 /polydopamine-coated MgZnYNd alloy corrosion rate in DMEM solution by Liu et al [51] .…”

Almost ten years ago, Lee et al. [13] formulated a universal adhesive coating based on observation of the strong attachment by mussels through their byssal threads to virtually all types of inorganic and organic surfaces. The amino acid compositions of the mussel foot proteins that generate the attachment are rich in catechol and amine groups. [13][14][15] These groups associate under marine conditions, forming strong covalent and noncovalent interactions with substrates. [13] This led to the idea that both catechol and amine groups were crucial in forming robust, wide spectrum adhesive nanolayers [16,17] and consequently dopamine was conceived as a powerful building block for spontaneous deposition of thin polymer films. The dopamine monomer is deposited onto unadulterated surfaces through self-assembly and oxidative cross-linking from mild pH aqueous solution in a rapid reaction. This results in a durable, nanoscale, conformal, and hydrophilic coating that can be readily modified to introduce specific surface chemistries for a particular application. [18][19][20][21][22] These bioinspired, polydopamine materials are chemically and structurally indistinguishable from eumelanins found in the human body, [23,24] providing excellent biocompatibility. Additionally, polydopamine has broad electromagnetic absorption and excellent photothermal energy conversion [25] as well as having ionic-electronic hybrid conductivity. [26] Along with the excellent coating performance, these properties provide a vast array of potential applications for polydopamine materials.In this article, we explain what is known about polydopamine and related catecholamine coatings; their formation, the adhesion mechanism, and their physicochemical properties and we also review the applications of these materials (Figure 1). Since 2011, there have been a number of reviews on this subject matter, including general reviews on the physicochemical properties of polydopamine coatings [11,20,[27][28][29] and their applications. [20,27,30] There are also a number of more specific reviews on the chemical synthesis and modulation of polycatecholamine coatings, [31] the biomedical applications of these coatings, [8,[32][33][34] their electronic properties, [26,35] the use of polydopamine to make films at fluid interfaces, [36] in hierarchically constructed particles, [33] and capsules, [30] exploitation of polycatecholamine coatings in membrane filtration, [37] polydopamine-derived carbon materials, [38] and the use of coordination chemistry in catechol-based materials. [39] Nonetheless, this area of research is growing so rapidly [25,27] that many recent Polydopamine and related polycatecholamines can be easily deposited onto almost any surface from mild, aqueous solution. This results in durable, nanoscale coatings that exhibit high biocompatibility and have useful chemical and electronic properties. Additionally, these materials can be readily chemically and physically modified, and consequently, they are used extensively for surface modification. This ...

“…It is known to stimulate the proliferation of osteoblasts and increase the new mineral deposition of cancellous bone, as it substitutes for the hydroxyl group in hydroxyapatite to form fluorapatite [27,28]. At present, a large amount of research has focused on MgF 2 coatings on magnesium and its alloys through chemical conversion using various concentrations of hydrofluoric acid and/or temperatures, which improved corrosion resistance and cytocompatibility [28][29][30][31][32].…”

In this study, films with different fluorine contents were prepared on an AZ31 magnesium alloy by using plasma electrolytic oxidation to study the corrosion resistance and cytocompatibility of the alloy. The morphology of the coating surface, phase, and chemical elements were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy-dispersive X-ray spectrometry (EDS). The changes in the corrosion resistance with different fluorine contents were investigated by electrochemical experiments, hydrogen evolution, and long-term immersion tests. In addition, murine fibroblast L-929 cells were adopted for in vitro cytotoxicity tests using the cell counting kit (CCK)-8 assay, and the morphology of the cells was observed simultaneously by inverted microscopy. The results showed that the main form of the fluorine ions in the plasma electrolytic oxidation coatings was magnesium fluoride (MgF2). In addition, the corrosion resistance and cytocompatibilities of the coatings were improved by the addition of fluoride ions. When the content of potassium fluoride reached 10 g/L, the cell compatibility and corrosion resistance were the best, a finding which provides a basis for the clinical applications of the AZ31 magnesium alloy in the biomedical field.
