“…131 In industries, titanium on a nanoscale is used for its antibacterial activities such as long storage of wool which would have bacterial growth due to moist environment. 132 Titanium as a nanomaterial is promising in both the medical field and industries due to its antibacterial performances. Toxicity studies are important to daily life such as sunscreen and cosmetics products, toxicity studies are important to prevent biological harms to the body.…”

The era of antibiotic resistance is a cause of increasing concern as bacteria continue to develop adaptive countermeasures against current antibiotics at an alarming rate. In recent years, studies have reported nanoparticles as a promising alternative to antibacterial reagents because of their exhibited antibacterial activity in several biomedical applications, including drug and gene delivery, tissue engineering, and imaging. Moreover, nanomaterial research has led to reports of a possible relationship between the morphological characteristics of a nanomaterial and the magnitude of its delivered toxicity. However, conventional synthesis of nanoparticles requires harsh chemicals and costly energy consumption. Additionally, the exact relationship between toxicity and morphology of nanomaterials has not been well established. Here, we review the recent advancements in synthesis techniques for silver, gold, copper, titanium, zinc oxide, and magnesium oxide nanomaterials and composites, with a focus on the toxicity exhibited by nanomaterials of multidimensions. This article highlights the benefits of selecting each material or metal-based composite for certain applications while also addressing possible setbacks and the toxic effects of the nanomaterials on the environment.

“…One of the areas of biomedical application of titania nanoparticle coatings is so-called "smart" textiles, which are able to purify themselves from organic matter and fungal attack, as well as to destruct bacteria under the influence of soft UV-radiation. Montazer et al [39] investigated the antifelting and antimicrobial features of TiO 2 treated wool samples against gram-negative and gram-positive bacteria. The fields of application of such materials are quite broad -from the medical staff wear and bed linen to bandaging materials.…”

A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT AbstractPresent work is devoted to investigation of structure and functional properties of hybrid nanomaterials based on the TiO 2 -modified cellulose fibers of cotton. The titania hydrosol was successfully prepared using the titanium tetraisopropoxide as precursor and the nitric acid as peptizing agent via the low-temperature sol-gel synthesis in aqueous medium and applied to cotton fabric. For cross-linking of titania nanoparticles to cotton the 1,2,3,4-butanetetracarboxylic acid (BTCA) was used as a spacer. The morphology and composition of the surface pure and TiO 2 modified cotton fibers were investigated by the Scanning Electron Microscopy (SEM). The cotton/TiO 2 composite was characterized by the dielectric permittivity.For the estimation of total titania concentration, all samples were calcined at 650°C. The antimicrobial activity of the treated TiO 2 cotton fibers was investigated against Escherichia coli as a model Gram -negative bacteria after exposure to UV-irradiation for 10 minutes.

“…The premise of using composite materials stems from the fact that zinc oxide (ZNPs) and titanium dioxide nanoparticles (TNPs) induce potent antibacterial and anticancer activities when applied in mill molar concentrations (Jones et al 2008;Yamamoto 2001;Zhang et al 2007;Brunet et al 2009;Han et al 2016;Montazer et al 2011;Savvova and Bragina 2010). We have previously demonstrated potent antibacterial and anticancer activities of ZNPs and TNPs prepared by multiple synthesis routes & V.

The study describes the antibacterial and anticancer activities of a nanocomposite prepared by mixing zinc oxide and titanium dioxide nanoparticles. The particle mixtures were analyzed by X-ray diffraction, Field emission scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, and dynamic light scattering techniques. Thus, analyzed samples were subject to disc diffusion method at various concentrations to analyze their antibacterial activities against two Gram-positive and two Gram-negative bacteria. The same samples were then analyzed for their anticancer activities on four different cell lines. The results indicate a synergistic effect of the nanocomposite on both antibacterial and anticancer properties when compared to their individual counterparts.
