“…151,152 Many studies have reported that TiO 2 nanotubes enhance the bone mineralization, osteoblast adhesion in vitro, and strong bone adhesion in vivo. 166 Jin and his coworkers found that TiO 2 nanotubes (<100 nm diameter) had excellent osteoblast adhesion properties with elongated nuclei and up-regulated alkaline phosphatase enzyme, which suggests excellent biocompatibility and interaction with bone tissue for orthopedic implants. [158][159][160] Ti-6Al-4V (Ti-Alloy) is the most common alloy used in medical implants 161 due to its excellent anti-corrosion properties caused by the spontaneous formation of a 2-3 nm oxide film on the alloy surface.…”

Titanium dioxide (TiO2) is one of the most abundantly used nanomaterials for human life. It is used in sunscreen, photovoltaic devices, biomedical applications and as a food additive and environmental scavenger. Nano-TiO2 in biomedical applications is well documented. It is used in endoprosthetic implants and early theranostics of neoplastic and non-neoplastic maladies as a photodynamic therapeutic agent and as vehicles in nano-drug delivery systems. Herein, we focus on the recent advancements and applications of nano-TiO2 in bio-nanotechnology, nanomedicine and photodynamic therapy (PDT).

“…Especially, metallic ions react with the ions in body fluid, and then this affect to the neighboring textures. To prevent this adverse effects, biomaterials are coating hydroxyapatite [Ca10 (PO4)6(OH)2-HAP] (Kwok et al 2009, Rath et al 2012, Benea et al 2014a, Benea et al 2015. HAP is widely known as a coating material, near identity of bone chemical composition and its talent to chemical bond conjuction bone smoothly for dental health and orthopedic implants a great of years.…”

In this research, hydroxyapatite (HAP) has been coated on the Ti6A14V alloy surface by electrophoresis method. In this electrophoresis method, NH4H2PO4 is taken as P precursor and Ca (NO3)2.4H2O is taken as Ca precursor to obtain HAP coating. Additionally, 5 N NaOH pre-treatment surface operation (PTSO) has been applied to Ti6A14V. PTSO are effective on clinging of HAP coating to the surface. The corrosion behaviours of uncoated and HAP coated samples are examined in simulated body fluid (SBF) after for holded 7, 14, 21 and 35 days in SBF. HAP coatings have obtained by electrophoresis method was not showed inhibition for preventing corrosion. The surface images of the samples were described by scanning electron microscope (SEM), energy dispersive X-ray analysis (EDX), and X-ray diffraction (XRD). From SEM images have been observed open pores and connections among pores in the coating, which increases osteointegration. It is noted in EDX analyses of the surfaces of the HAP coated samples that there is Ca, O and P on the surface. It is seen in XRD analysis of HAP coated samples that there are TiO2, HAP and calcium phosphate structures on the surfaces.

“…Unfortunately, these alloys exhibit often a fail after long-term use in the human body due to an incomplete osseo-integration [9] and ions release. Therefore, to overcome these problems, the modification of the smooth surface of Ti-alloys have received considerable attention in order to improve the biocompatibility of titanium and to enhance the bone growth, this modification was carried out by various coating methods such as: thermal oxidation [10,11], electrochemical anodization [12][13][14][15], hydroxyapatite coating [16][17][18] and alkaline treatment with NaOH [19,20], etc.…”

Nanostructured Titania layers formed on the surface of titanium and titanium alloys by anodic oxidation play an important role in the enhancement of their biocompatibility and osseointegration in the human body. For this purpose, we aimed to study in the current work the structural and electrochemical properties of amorphous and crystallized nanostructured TiO2 thin films elaborated on Ti6Al4V substrate by electrochemical anodization in fluoride ions (F -) containing electrolyte at 10 V during 15 min and heat treated in air at 550 °C for 2 h. The morphology, chemical composition and phase composition of synthesized layers were investigated using field emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD). The corrosion resistance improvement of both as-anodized and annealed titania layers was evaluated in 0.9 wt. % NaCl solution with pH  6.4 at room temperature by means of open circuit potential (Eoc),potentiodynamic polarization (PDYN) and electrochemical impedance spectroscopy (EIS).
