“…[260][261][262][263][264] In a recent study, PMMA and PMMA-alumina composites have been coated on stainless steel via EPD to improve the bioactivity and osteoconductive properties. 265 They were able to achieve a homogeneous and porous coating in both cases, where PMMA coating had maximum thickness of 2 lm and PMMA-alumina had a coating thickness of 10 lm. The ALP activity studies confirmed the bioactivity and osteoconductive capacity of both coated surfaces, where maximum bioactivity was found for composite-coated surfaces followed by PMMA-coated surfaces.…”

The world of biomaterials has been continuously evolving. Where in the past only mono-material implants were used, the growth in technology and collaboration between researchers from different sectors has led to a tremendous improvement in implant industry. Nowadays, composite materials are one of the leading research areas for biomedical applications. When we look toward hard tissue applications, metal-based composites seem to be desirable candidates. Metals provide the mechanical and physical properties needed for load-bearing applications, which when merged with beneficial properties of bioceramics/polymers can help in the creation of remarkable bioactive as well biodegradable implants. Keeping this in mind, this review will focus on various production routes of metal-based composite materials for hard tissue applications. Where possible, the pros and cons of the techniques have been provided.

“…[96a,101] Sodium cholate was used as a charged dispersant for the EPD of polymethylmethacrylate (PMMA) and composite PMMA-alumina films for biomedical applications. [102] It was found that sodium cholate facilitated solubilization of PMMA in water. Moreover, investigations revealed interactions of sodium cholate with PMMA and alumina, which allowed for their deposition and codeposition.…”

“…Moreover, investigations revealed interactions of sodium cholate with PMMA and alumina, which allowed for their deposition and codeposition. [ 102 ] These studies showed that BSs are versatile dispersants and codispersants for EPD of different materials and composites. It was shown that the use of BSs as charging and dispersing agents is an important strategy for the EPD of carbon materials, such as diamonds, CNTs and graphene, biocompatible polymers, and inorganic materials.…”

Applications of bile acids (BAs) and bile salts (BSs) in the nanotechnology of functional materials are described. The exceptionally strong solubilization and dispersion power of BAs/BSs is a key factor for the solubilization of dyes, drugs, and polymers for electronic, optical, and biomedical devices, fabrication of composites, based on carbon nanotubes, graphene, diamonds, quantum dots, and polymers for applications in energy storage devices, coatings for corrosion protection of metals, sensors and electronic devices. BAs/BSs have attracted attention for synthesis, design, and surface modification of advanced materials. BAs/BSs are used as reducing, capping, chelating and dispersing agents for the synthesis of nanoparticles of metals and alloys, and low temperature synthesis of stoichiometric nanostructured complex oxides. BAs/BSs exhibit unique selfassembly properties, which are successfully used for the template synthesis of functional nanoparticles of controlled shapes. Particularly important are applications of BAs/BSs in the fabrication of dye sensitized solar cells with enhanced efficiency. Electrochemical strategies are discovered for the deposition of BA films and composites. Of particular interest are the unique gel-forming properties of BAs/BSs, which provide a basis for the synthesis of nanoparticles of controlled size and fabrication of novel materials with advanced functionality.

“…Moreover, composite materials were electrodeposited from their dispersions in bile salt solutions. Sodium cholate was used as a multifunctional solubilizing, charging, dispersing and film‐forming agent for the fabrication of polymethylmethacrylate and composite polymethylmethacrylate‐alumina films by electrophoretic deposition (D'Elia et al, 2020). These studies provided evidence of PMMA association with cholate anions in solutions.…”

Bile acids (BAs) are physiologically important biosurfactants (Singh, Metrani, Shivanagoudra, Jayaprakasha, & Patil, 2019), which solubilize cholesterol, lipids, proteins, fatty acids, monoglycerides and vitamins in a human body. The strong solubilization power of BAs is related to their amphiphilic chemical structure, which is fundamentally different from the structures of other surfactants. As a general feature, natural BAs molecules have a steroid nucleus with concave hydrophilic and convex hydrophobic sides, containing OH and methyl groups, respectively (Figure 1a and Table 1). The chemical structures of BAs contain a short hydrocarbon chain with COOH or SO 3 H end groups. As a result, dissociated BAs molecules exhibit anionic properties in solutions. Properties of BAs are influenced by the number of OH groups bonded to a steroid core and nature of anionic groups. Modifying the hydroxyl or carboxyl groups of BAs creates a diverse set of BA-based compounds, maintaining some original properties and introducing novel properties as well. The unique distribution of hydrophilic and hydrophobic domains allows these molecules to self-organize into supramolecular assemblies in water. BAs salts form mixed micelles (Figure 1b) with various water-insoluble molecules and facilitate their dissolution. Moreover, BAs allow dispersion of hydrophobic materials, such as carbon nanotubes (Ata, Poon, Syed, Milne, & Zhitomirsky, 2018). The bifacial amphipathic BAs molecules act as compatibilizing agents between the water-insoluble
