“…Ti alloys are bioinert and do not bond well to bones after implantation into the human body [9]. In recent years, researchers have adopted multiple surface modification methods, including electrospinning [10], sol-gel [11], sputtering [12], electrophoretic deposition [13], plasma electrolytic oxidation (PEO) [14][15][16], and anodic oxidation [17] methods. Among them, the anodization method can produce ordered TiO 2 nanotubes, which have a large specific surface area [18].…”

Although titanium (Ti) alloys have been widely employed as biomedical materials, they cannot achieve satisfactory osseointegration when implanted in the human body due to their biologically inert nature. Surface modification can enhance both their bioactivity and corrosion resistance. The present study employed a Ti–5Nb–5Mo alloy with a metastable α″ phase. This alloy may undergo phase changes after conventional high-temperature heat treatment, which can deteriorate its properties. This study heat-treated the anodized Ti–5Nb–5Mo alloy by using a low-temperature hydrothermal or vapor thermal method to analyze the effects of heat treatment on its apatite induction. The results revealed that the porous nanotube structure on the surface of the alloy was transformed into anatase nanoparticles after hydrothermal or vapor thermal treatment at 150 °C for 6 h. After immersion in simulated body fluid (SBF) for 7 days, the amount of apatite deposited on the surface of the vapor thermal-treated alloy exceeded that on the hydrothermal-treated alloy. Therefore, post-heat treatment of anodized Ti–5Nb–5Mo by using the vapor thermal method can enhance its apatite inductivity without altering its structure.

“…Such sol creates an interconnected polymeric network upon aging, known as gel [43]. The gel is used to form a film or a coating over a substrate for a wide range of applications such as superhydrophobic surfaces, gas sensing [44], integrated optics/photonics [45][46][47][48][49][50], electronic devices [51][52][53][54][55], biomedical [49,56,57] and pollution adsorption [58]. Additionally, the micro-patterning of such sol-gel films can be a promising candidate for future display and optoelectronic applications [59].…”

Particle-coated liquid entities are the basis of many useful products, such as foams, emulsions, bijels, and liquid marbles. Particles stabilized at the liquid-air interface have been widely explored during the past two decades. Such interfaces usually consist of micro- to nano-sized particles that often tend to aggregate and lose transparency as well as the smoothness of the interface. Recently, these obstacles have been overcome by using sol-gel-derived silica nanoparticle coating. Sol-gel-derived nanoparticles offer a monolayer structure at the interface with high transparency and reproducibility. This paper critically reviews three sol-gel-derived liquid entities: Liquid marbles, Liquid plasticine, and nanoparticle-coated flat interface. Liquid marble, a particle-covered droplet, was significantly explored for its application as a container in many biological and chemical processes. Unlike powder-derived liquid marble, sol-gel-derived liquid marble can be formed into any desired shape, commonly known as liquid plasticine. Monolayer-covered sol-gel entities also offer a simple physical platform for investigating many fundamental properties of particle-coated interfaces. In the present review, starting from its preparation to the application, all critical aspects are summarized. Some unaddressed issues compared to the powder LM are also discussed for future research.

“…Nanocomposite coatings of hydroxyapatite along with carbon nanotube, zirconia, bioactive glass, chitosan, TiO 2 , collagen, etc., is investigated to avoid the problems related to HAP. Nanocomposite of alumina, graphene and hydroxyapatite coatings were carried out on Ti-6Al-4V of bone implant to increase tribo-mechanical and antibacterial properties [29]. There are many other complications of surface-modified implants which have been noticed because of poor integration of implants, mechanical instability and infections.…”
