“…For TiO2 (figure 1a), the diffraction picks are : 2θ= 25,32°, 37,82°, 47,07°, 53,97°, 55,15°, 62,75°, 68,72°, 70,30° and 75,12° the projections of these values on a crystallographic plane gives the following (hkl) coordinates : (101), ( 004), ( 200), ( 105), ( 211), ( 204), ( 116), ( 220) and ( 215). Based on these results we conclude that the crystallographic plane corresponds to Anatase phase (JCPDS 21-1272), which confirms that our TiO2 is mostly Anatase [36]. The g-C3N4 analysis results (figure 1b),…”

“…[80,81] To achieve aspect (i), photocatalysts such as titanium dioxide (TiO 2 ) and zinc oxide (ZnO) have been shown to have high antimicrobial properties. [82,83] For example, Nguyen et al [84] recently developed a facemask made from a polypropylene filter coated with ZnO/TiO 2 bilayer. Interestingly, the facemask is attached with a separate UV-LEDs layer to supply UV light when necessary for photocatalytic disinfection.…”

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was responsible for the outbreak of coronavirus disease . The respiratory illness has rapidly spread worldwide and has claimed millions of lives. Although most countries have entered the endemic phase, health authorities warned that future variants could be more virulent than the existing ones. Since clinical trials of antiviral drugs for COVID-19 may last even a year before approval, developing alternative approaches to combat the virus becomes mandatory. Previ-ously, carbon nanotubes (CNTs) have exhibited an impressive track record in controlling numerous viral diseases, including COVID-19. In this article, we review recent applications of CNTs for the prevention, detection, and treatment of COVID-19. We highlight the strategies and prospective developments of CNTs in producing personal protection equipment (PPE), vaccines, immune-triggering, development of biosensors and therapeutic strategies. Finally, the challenges, limitations, and future outlook of CNTs in combating COVID-19 are also discussed.

“…The goal of this study was to modify TiO2 NPs that have been engineered using ZnO NPs and then adorned with CdS NPs using a hydrothermal technique. The sensing and cytotoxicity activity of TiO2/ZnO-CdS nanocomposites (NCs) was investigated further after their manufacture (Luo et al, 2015;Pragathiswaran et al, 2015Pragathiswaran et al, , 2022Cruz et al, 2017).…”

In this study the sol-gel method was used to create a composite of titanium oxide nanoparticles (TiO2- NPs) @ ZnO nanoparticles (TiO2 @ ZnO). Using a hydrothermal process, the TiO2@ZnO nanocomposite (NC) was changed via wreathing cadmium sulphide nanoparticles (CdS NPs) (TiO2@ZnO–CdS). Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDAX) were employed to investigate the TiO2@ZnO–CdS NC. The CdS NPs are uniformly distributed over the TiO2@ZnO NC. According to FESEM analysis. TiO2@ZnO–CdS NC is used to detect imidazole at low concentrations and assess cytotoxicity. The TiO2@ZnO–CdS NC has been found to have the best electrochemical sensing activity and considerable cytotoxicity against A549 lung cancer cells.
