“…For example, solgel‐derived NBG particles have been used to coat different materials (porous ceramics, metals) to achieve improved mechanical properties and high bioactivity . More recently, Sebdani and Fathi fabricated novel hydroxyapatite–forsterite–BG nanocomposite coating via a solgel method and evaluated its mechanical properties. It was stated that improvement of the mechanical properties could be obtained with increasing forsterite content.…”

This review focuses on recent advances in the development and use of nanoscale silicate bioactive glasses for medical applications. In the context of materials for bone substitution, dental applications, and bone tissue engineering, nanoscale bioactive glasses have been gaining attention due to their expected superior osteoconductivity when compared with conventional (micrometer-sized) bioactive glass materials. A detailed overview of recent developments in the field of nanoscale bioactive glasses will be given, including a summary of common fabrication methods and diverse application areas which include tissue engineering scaffolds and coatings, drug delivery devices, and dentistry. The nanofeatures characteristic of this type of bioactive glasses and the possibilities to expand their use in biomedical applications (nanomedicine) are highlighted.

“…Recently, many attempts to combine HAP with bioactive glasses have been reported, such as sol-gel [27,28,29,30], hot-press sintering [31,32], pressureless sintering [33,34], and SPS [35,36,37]. HAP composite produced with sol-gel has been mainly used as a porous coating on metallic implants in orthopedic and dental applications to combine the excellent mechanical properties of metals and bioactivity of hydroxyapatite [28]. The higher temperature (1200–1350 °C) required for the conventional sintering (hot-press sintering, pressureless sintering) of this composite system results in the complete crystallization of bioglass and excessive reactions between bioglass and HAP, which are suspected to delay the bioactivity response [35].…”

Hydroxyapatite (HAP) has excellent biocompatibility with living bone tissue and does not cause defensive body reactions, therefore, it has become one of the most widely used calcium phosphate materials in dental and medical fields. However, its poor mechanical properties have been a substantial challenge in the application of HAP for the replacement of load-bearing or large bone defects. Laminated HAP–45S5 bioglass ceramics composites were prepared by the spark plasma sintering (SPS) technique. The interface structures between the HAP and 45S5 bioglass layers and the mechanical properties of the laminated composites were investigated. It was demonstrated that there was mutual transfer and exchange of Ca and Na atoms at the interface between 45S5 bioglass/HAP laminated layers, which contributed considerably to the interfacial bonding. Due from the laminated structure and strong interface bonding, laminated HAP–45S5 bioglass is recommended for structural applications.

“…HA coating over silicon wafer using sputtering by Ligot et al 44 yielded Young's modulus of 147 AE 10 GPa and hardness of 10 AE 1 GPa. Sebdani and Fathi 51 used composite material made of HA, forsterite, and bioactive glass for coating over stainless steel (SS 316L) using sol-gel technique and found the Young's modulus to be in the range of 46-96 GPa and hardness in the range of 2.4-3.4 GPa.…”

Biocompatible metallic alloys (stainless steel, Ti-alloy, Co–Cr alloys, etc.) have been frequently used for various biomedical implants. Being biocompatible, complications like implant corrosion, body inflammation, organ pain, local infection, and cytotoxicity cannot be avoided. Hydroxyapatite, a common biomaterial, is used in the form of powders, coatings, and composites for biomedical applications. But poor adhesion, poor load-bearing capacity, high dissolution, poor wear resistance, natural fragility, etc. are the few hindrances in the use of hydroxyapatite coating over implants. Hence, there is a need to focus on the development of alternative biomaterials and their coatings for metallic (orthopedic, dental, metallic stents, pacemakers, etc.) implants. To avoid various complexities and to improve the biocompatibility of metal implants, the coating of forsterite and its composites are being used nowadays. Techniques like dip coating, plasma spraying, and electrophoretic deposition are employed for such coatings. In this paper, a review based on methods of preparation of forsterite has been done. For the preparation of forsterite powder, various studies have reported the sintering temperature range to be 800–1450 ℃ and the crystallite size from 10 nm to 100 µm. The forsterite and its composites coating over Ti-alloy and stainless steel have also been reported. This paper also compares the mechanical and biological properties of forsterite and hydroxyapatite. It has been observed that the mechanical properties (hardness, fracture toughness, Young’s modulus, and compressive strength), and biological properties (biocompatibility and bioactivity) of forsterite are favorable for the biomedical implant coating.
