“…On the contrary, the second approach allows the distribution of the cobalt (II, III) oxides in the interior of the TiO2 that would prevail over the above issue and enhance the composite material performance. More recently, Wang et al [ 201 ] and Kobylański et al [ 202 ] examined the fabrication and characterization of Co3O4-doped TiO2 NTs electrodes and TiO2-Co x O y composite NTs via a single-step electrochemical anodization process for visible-light-induced photocatalytic reaction, respectively. The diameter, and length of the MONs are almost unchanged with the increase of Co content, thus the diameter and length of the TiO2, TiO 2 –3%Co, TiO 2 –6%Co, and TiO 2 –9%Co nanotubes are around 61.9 nm and 1.7 μm, 57.5 nm and 1.6 μm, 57.9 nm and 1.6 μm, and 55.0 nm and 1.6 μm, respectively [ 201 ].…”

Another recent work indicated that the increase of the water content in the electrolyte from 2 to 10% caused the development of TiO2-Co x O y composite NTs with larger diameters (88–125 nm for 2–10% H2O, respectively).…”

Nanomedicine has seen a significant rise in the development of new research tools and clinically functional devices. In this regard, significant advances and new commercial applications are expected in the pharmaceutical and orthopedic industries. For advanced orthopedic implant technologies, appropriate nanoscale surface modifications are highly effective strategies and are widely studied in the literature for improving implant performance. It is well-established that implants with nanotubular surfaces show a drastic improvement in new bone creation and gene expression compared to implants without nanotopography. Nevertheless, the scientific and clinical understanding of mixed oxide nanotubes (MONs) and their potential applications, especially in biomedical applications are still in the early stages of development. This review aims to establish a credible platform for the current and future roles of MONs in nanomedicine, particularly in advanced orthopedic implants. We first introduce the concept of MONs and then discuss the preparation strategies. This is followed by a review of the recent advancement of MONs in biomedical applications, including mineralization abilities, biocompatibility, antibacterial activity, cell culture, and animal testing, as well as clinical possibilities. To conclude, we propose that the combination of nanotubular surface modification with incorporating sensor allows clinicians to precisely record patient data as a critical contributor to evidence-based medicine.

“…As is known, nano-TiO 2 has better chemical properties and photon characteristics due to its good absorbability and lower electron/hole recombining rate, and can be used as a new kind of electrical catalyst material [16,17,18]. There have been many reports on the application of nano-TiO 2 composite polymers in the electrocatalysis of organic materials [19], including a study by the present research group [20].…”

A novel poly-geminal dicationic ionic liquid (PGDIL)-TiO2/Au composite film electrode was successfully prepared by electrochemical polymerization of 1,4-bis(3-(m-aminobenzyl)imidazol-1-yl)butane bis(hexafluorinephosphate) containing polymerizable anilino groups in the electrolyte containing nano-TiO2. The basic properties of PGDIL–TiO2/Au composite films were studied by SEM, cyclic voltammetry, electrochemical impedance spectroscopy, and differential pulse voltammetry. The SEM results revealed that the PGDIL–TiO2 powder has a more uniform and smaller particle size than the PGDIL. The cyclic voltammetry results showed that the catalytic effect on electrochemical oxidation of hydroquinone and catechol of the PGDIL–TiO2 electrode is the best, yet the Rct of PGDIL–TiO2 electrode is higher than that of PGDIL and TiO2 electrode, which is caused by the synergistic effect between TiO2 and PGDIL. The PGDIL–TiO2/Au composite electrode presents a good enhancement effect on the reversible electrochemical oxidation of hydroquinone and catechol, and differential pulse voltammetry tests of the hydroquinone and catechol in a certain concentration range revealed that the PGDIL–TiO2/Au electrode enables a high sensitivity to the differentiation and detection of hydroquinone and catechol. Furthermore, the electrochemical catalytic mechanism of the PGDIL–TiO2/Au electrode was studied. It was found that the recombination of TiO2 improved the reversibility and activity of the PGDIL–TiO2/Au electrode for the electrocatalytic reaction of HQ and CC. The PGDIL–TiO2/Au electrode is also expected to be used for catalytic oxidation and detection of other organic pollutants containing –OH groups.
