One-dimensional titanium dioxide (TiO) nanotubes (TNTs) doped with silver (Ag) (% 5) were synthesized via two-step hydrothermal method. These nanotubes were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The impact of Ag-doped TiO nanotubes as antibacterial agents against three strains of Gram positive Staphylococcus aureus and a strain of Gram negative Escherichia coli was also investigated. XRD, FT-IR and Raman spectroscopy results showed that nanotubes were complete anatase phase. The potential biocidal effect of nanotubes to different S. aureus strains and E. coli was obtained.

Exosomes have emerged as a powerful biomarker for early cancer diagnosis, however, accurately detecting cancer-derived exosomes in biofluids remains a crucial challenge. In this study, we present a novel label-free electrochemical biosensor utilizing titanium dioxide nanotube array films (TiONTAs) for the sensitive detection of exosomes in complex biological samples. This innovative biosensor takes advantage of the excellent electrochemical properties of TiONTAs and their specific interactions with the phosphate groups of exosomes.

The preparation strategy is the important factor to obtain the effective photocatalyst, and the thermal decomposition could be used to prepare photocatalysts with high crystallinity and photoactivity. In this paper, thermal decomposition method was used to deposit CuO nanoparticles on TiO nanotube arrays (TiO NTs), and the TiO NTs/CuO exhibited remarkably high visible light absorption and photoelectrocatalytic performances toward dye degradation and Cr(VI) reduction. The potential degradation pathway and toxicities of rhodamine B (RhB) dyes and intermediates were investigated.

The current work outlines the preparation of a TiO nanotube (NT) layer electrochemically formed on the surface of a clinically-relevant titanium alloy anodisation. This NT layer was subsequently modified alternating current electrodeposition to incorporate copper micro- and nanoparticles on top of and within the NTs. Physical characterisation of the NT layer and the copper-incorporated NTs was carried out through analysis of the surface morphology, elemental composition, crystallinity, and stability SEM, EDX, XRD, and ICP-OES, respectively.

We present a novel approach for enhancing photocatalytic efficiency by developing polyaniline (PANI) and polyindole (PIN)-coated TiO nanotubes (TNT) through a combination of chemical oxidation and hydrothermal processes. The PANI-PIN coating was systematically applied to both the internal and external surfaces of the nanotubes to enhance the photocatalytic active sites and optimize pollutant adsorption. The dual-coated structure enhances the interaction with pollutants, facilitating a more efficient degradation of 4-nitrophenol (4-NP) when exposed to visible light.
