“…Among the many materials with antibacterial properties, titanium(IV) oxide deserves particular attention, in view of properties such as good chemical and thermal stability, as well as photocatalytic activity [ 15 ]. The first report on the biocidal properties of TiO 2 was published in 1985 by Matsunaga et al [ 16 ].…”

The TiO2-Fe3O4 composite materials were fabricated via the hydrothermal-assisted technique. It was determined how the molar ratio of TiO2 to Fe3O4 influences the crystalline structure and morphology of the synthesized composite materials. The effect of the molar ratio of components on the antibacterial activity was also analyzed. On the basis of XRD patterns for the obtained titanium(IV) oxide-iron(II, III) oxide composites, the two separate crystalline forms—anatase and magnetite —were observed. Transmission electron microscopy revealed particles of cubic and tetragonal shape for TiO2 and spherical for Fe3O4. The results of low-temperature nitrogen sorption analysis indicated that an increase in the iron(II, III) oxide content leads to a decrease in the BET surface area. Moreover, the superparamagnetic properties of titanium(IV) oxide-iron(II, III) oxide composites should be noted. An important aim of the work was to determine the antibacterial activity of selected TiO2-Fe3O4 materials. For this purpose, two representative strains of bacteria, the Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus, were used. The titanium(IV) oxide-iron(II, III) oxide composites demonstrated a large zone of growth inhibition for both Gram-positive and Gram-negative bacteria. Moreover, it was found that the analyzed materials can be reused as antibacterial agents in three consecutive cycles with good results.

“…Although the sol-gel based TiO 2 particles of large area have been applied for various biological applications ( Amanulla et al., 2019 ; Chegeni, Pour & Dizaji, 2019 ; Dinesh, Suresh Yadav, Kannadasan & Rasool, 2017 ), a deeper study about cytotoxic effect should be performed to guarantee their potential impact on environmental health and safety ( Rashid et al., 2021 ).…”

Antiviral hydrophobic cellulose-based cotton or non-woven fabrics containing mesoporous TiO 2 particles were developed for potential use in healthcare and in other contaminated environments. Hydrosols made with the sol-gel method using two different amounts of the Ti precursor were applied to cotton and non-woven fabrics and their virucidal effect on Murine Coronavirus (MHV-3) and Human Adenovirus (HAdV-5) was evaluated under indoor light irradiation. The results show 90% reduction of HAdV-5 and up to 99% of MHV-3 in non-woven fabric, and 90% reduction of MHV-3 and no reduction of HAdV-5 in cotton fabric. The antiviral activity was related to the properties of the TiO 2 powders and coatings characterized by BET surface area, DRX, DLS, FTIR, DRS, SEM, TEM and water contact angle. The hydrophobic characteristic of the treated fabrics and the high surface area of the TiO 2 particles favor interaction with the virus, especially MHV-3. These results demonstrate that non-woven fabric and cotton, coated with TiO 2 , can be highly effective in preventing contamination with MHV-3 and HAdV-5 viruses, particularly for applications in healthcare indoor environments.

Today, nanoparticles have attracted the attention of many researchers due to their special properties as well as their many technological applications. Among these, titanium dioxide nanoparticles have many important applications in various industries due to their excellent optical, electrical and catalytic properties. These applications include use in industrial pigments, as photocatalysts in environmental cleansing, in sunscreens to protect the skin, in photovoltaic applications for solar cells, sensors, in electronic device components, and many more. Two important properties of this material that make it very efficient and useful in life are its photocatalytic and superhydrophobic properties. These two properties are used to purify water and wastewater, eliminate air pollution and buildings, accelerate photochemical reactions such as hydrogen production, fabricate surfaces and layers and self-cleaning glass. The properties of titanium dioxide nanoparticles are strongly dependent on the size of the doped particles, elements or compounds and the surface modifications made on them, which in turn are influenced by the nanoparticle synthesis method. For this reason, methods for the synthesis of titanium dioxide nanoparticles have received much attention today. As the size of the material gets smaller and smaller and reaches the nanoscale, new physical and chemical properties show up. Among the unique properties of nanomaterials, the motion of electrons and holes in semiconductor nanomaterials is dominated by quantum constraint, and the transfer properties of phonons and photons are strongly influenced by the size and geometry of the material. The effective surface area and surface to volume ratio increase with decreasing the material size. High effective levels are achieved by small particles, which will be useful in many 2TiO-based types of equipment in which the interaction of the common surface of the material is important.
