“…To improve the thermal stability, the as-synthesized nanotubes were calcined at different temperatures for 1 h. The appearance of white color powder indicates the formation of TNT. The CoHCF@TNT was prepared by using an equimolar concentration of CoCl 2 ·6H 2 O and K 3 [Fe(CN) 6 ] containing 0.05 M KCl solution in presence of 100 mg of TNT [39]. Finally, the CoHCF@TNT was thoroughly washed with ultrapure water to remove the physisorbed ions.…”

The cobalt hexacyanoferrate-decorated titania nanotube (CoHCF@TNT) was prepared by dispersing 100 mg of titania nanotube (TNT) to a solution of an equimolar concentration of CoCl 2 · 6H 2 O and K 3 [Fe(CN) 6 ] containing 0.05 M KCl solution (35 mL). The TNT was synthesized by hydrothermal method using Degussa P-25 TiO 2 in 2 M NaOH as reported in the literature. The CoHCF@TNT was isolated and characterized by DRS-UV, FE-SEM, FT-IR, and XRD analysis. The electrochemical behavior of the CoHCF@TNT was carried out in 0.1 M phosphate buffer. The CoHCF@TNT modified system showed an excellent electron transfer mediator for the oxidation of hydrazine at +0.5 V versus Ag wire. The proposed method can be utilized for the amperometry detection of hydrazine from environmental samples. A calibration plot was constructed by plotting the concentration of hydrazine against the peak current. The current response was linear in the ranges of the hydrazine concentration from 5 × 10 −4 M to 2.5 × 10 −3 M with a slope of 72.8 μAmM −1 and the linear correlation coefficient of 0.9972. The detection limit was found to be 1 × 10 −3 M.

“…The diameter of TNT was measured by SEM and the formation of tubular nanostructure with the average diameter of 50 nm which was confirmed from SEM studies. The change in morphology of TNT was noted after the deposition of NiHCF [20]. The elemental composition of the composite was confirmed from EDAX analysis (Figure isn't shown here).…”

The nickel hexacyanoferrate decorated titanium oxide nanotube (NiHCF@TNT) was prepared by ion exchange method by mixing of nickel ion modified titanium oxide nanotube with a known amount of potassium ferricyanide under stirring over a period of 5 h. The resulting product was isolated and then characterized with XRD, FT-IR and SEM. The electrochemical behaviour of NiHCF@TNT was investigated by cyclic voltammetry using chitosan as stabilizing agent. The electrocatalytic property of chitosan protected NiHCF@TNT was carried out on electrochemical oxidation of paracetamol and caffeine simultaneously. The proposed method may be applied for the electrochemical detection of paracetamol in drug samples. _______________________________________________________________________________

“…With regard to the shape of nanoparticles, CNTs are the main competitors of TiNTs for drug delivery. , However, they have several drawbacks: they are insoluble in most solvents, and in contrast to TiNTs, they have closed ends . Several nanomaterials compared to TiNTs demonstrate a similar kinetic of clearance but accompanied with high dramatical sings of toxicity and perturbation of the liver, heart, and kidney functions. ,, Interestingly, the determination of biomarkers, related to the liver, kidney, and spleen functions, evidenced the safety/toxicity risk of TiNTs. Indeed, activities of typical biomarkers of hepatic cytolysis including circulating ALAT and ASAT activities increased 1.5 times compared to the control group from 6 h until 7 days.…”

Titanate nanotubes (TiNTs) produced by the static hydrothermal process present a promising nanosystem for nanomedicine. However, the behavior of these nanotubes in vivo is not yet clarified. In this work, for the first time, we investigated the toxicity of these materials, their pharmacokinetic profile, and their biodistribution in mice. A high dose of TiNTs (45 mg/kg) was intravenously injected in mice and monitored from 6 h to 45 days. The histological examination of organs and the analysis of liver and kidney function markers and then the inflammatory response were in agreement with a long-term innocuity of these nanomaterials. The parameters of pharmacokinetics revealed the rapid clarification of TiNTs from the bloodstream after 6 h of the intravenous injection which then mainly accumulated in the liver and spleen, and their degradation and clearance in these tissues were relatively slow (>4 weeks). Interestingly, an important property of these materials is their slow dissolution under the lysosome acid environment, rendering them biodegradable. It is noteworthy that TiNTs were directly eliminated in urine and bile ducts without obvious toxicity in mice. Altogether, all these typical in vivo tests studying the TiNT pharmacokinetics, toxicity, and biodistribution are supporting the use of these biocompatible nanomaterials in the biomedical field, especially as a nanocarrier-based drug delivery system.
