Abstract
Nowadays, titanium and alloy materials are encouraged for biomedical applications. Fabrication of the passive layer over the titanium materials is limited. Typically, a plain titanium sample is not suitable for bioimplant applications because the adhesion of biological elements like blood cells, tissues, and bones is poor. The use of surface-modified titanium resolves this issue. Surface modifications on titanium by electrochemical methods are simple and cost-effective. The addition of water to the ethylene-based electrolyte-enhanced the oxidation process to increase the length of the nanotubes. Surface morphological analysis shows that the length of the nanotubes has been increased, nanoindentation analysis delivers that increasing the length has been increased the hardness level, and corrosion analysis indicates that the length of nanotubes encouraged the corrosion resistance. Potentiodynamic polarization, Bode and Nyquist plots were models fit analyzed with equivalent electrical circuits. Sample cell viability was characterized with NIH-3T3 cells using an inverted microscopy analyzer.

Summary
Biomedical device fabrication processes have been gaining significant attention from researchers. Titanium alloys are best suited to fabricate biomedical implants as they possess good adaptability in the biological environment. Different techniques are available for material surface modification like physical vapour deposition, chemical vapour deposition, sol-gel, hydrothermal, and electrochemical anodization. From the techniques mentioned above, the electrochemical anodization is the easiest and feasible technique for surface modification. Electrochemical anodization needs a simple working setup that consumes low space and energy to fabricate the stable and compact TiO2 nanotubes on the surface of the Ti foil [2]. The presence of the ion particles in the electrolyte provides continuous etching according to the theory of field-assisted dissolution, resulting in the oxide layers formed over the nanotubes [3]. The fluorine-based electrolytes were observed to produce better etching, according to Zwilling et al 1999
