“…According to a previous study, the surface functionalization and doping agents in oxide, sulfide, and nitride based nanomaterials enhance the structural, electrical, optical, and biological performance. − The TiO 2 nanoparticles exist in three different structural phases which include rutile, brookite, and anatase . The rutile and anatase phases are the most common compared to brookite.…”

The current research is related to the synthesis of different concentrations (0, 3, and 7 wt %) Zn doped TiO 2 -NPs by using the coprecipitation method. The rutile, anatase crystal structure appeared on different diffracted peaks in TiO 2 -NPs, and the crystallite size (12 to 24 nm) was calculated by using XRD analysis. The spherical, irregular, porous grainlike surface morphology was observed by SEM analysis, and the identification of different functional modes such as hydroxyl, −C−O, −C−O−C, and Ti− O−Ti attached on the surface of the spectrum was examined via FTIR analysis. After that, the increased absorbance of TiO 2 -NPs by increasing the Zn concentration in TiO 2 -NPs was observed by UV−visible analysis. After that, the well diffusion method was performed to measure antibacterial activity, and the MTT assay was used to investigate anticancer activity against the HepG2 cell line. It was observed that the inhibition zone of S. aureus and E. coli increased by increasing the concentration of Zn-doped TiO 2 -NPs from 2 to 32 mm. The 7 wt % Zn-doped TiO 2 -NPs provided significant anticancer activity against the liver cancer cell line and antibacterial activity. In the future, Zn doped TiO 2 -NPs can be used for in vitro analysis against different microbial and animal models for the treatment of cancer.

“…Silver in the nanoscale range of 10-20 nm in the matrix of 0.6 % sodium alginate in an aqueous medium has an antibacterial and fungicidal effect at low concentrations, which may be due to the larger specific surface of nanoparticles in this composition and the increased area of contact of nanosilver with microorganisms [4]. Hence the possibility of reducing the toxic effect of silver as a metal a hundred times while maintaining its bactericidal properties, including for the remaining viable but uncultivable micro-organisms [2,5]. Nanosilver offers a wide opportunity to create highly effective drugs and their wide use in medicine and other areas of human activity.…”

“…The application of nanomaterials in textiles has been gradually increasing with the development of fabrication technology. Silver is one of the most well-explored nanomaterials in functional textiles due to its broadspectrum and high antimicrobial activity, [1][2][3][4][5] strong ultraviolet (UV) shield effect, [6][7][8][9] hydrophobicity, [10][11][12] self-cleaning ability, [13][14][15] and electromagnetic shielding property. [16][17][18][19][20] To achieve the above functions, textiles can be functionalized by coating with silver nanoparticles during the fabrication process of fibers or textiles.…”

Except for conventional functions, special textiles doped with nanoscale particles have shown quite attractive properties, such as antibacterial activity, deodorization, hydrophobicity, and ultraviolet/electromagnetic protection. However, facile and reliable methods for quality assessment of those functional nano-textiles are remarkably demanded for market surveillance and consumer protection. Herein, a novel detection method of silver in textiles was established for the comprehensive detection and a practical flow chart was also demonstrated as an experimental pathway including pretreatment, qualitative and quantitative analysis. The optimal ashing parameter (450°C for 1 h) in the pretreatment process was explored to improve detection sensitivity. The qualitative analysis was performed through X-ray diffraction for crystallinity, scanning electron microscopy for morphology, and energy-dispersive X-ray spectroscopy (EDS) for elements. The real existent status of the silver components could be decided via the flow chart. As shown with the detected sample, the content was calculated by the weight loss at 1050–1500°C from thermogravimetric analysis measurement and the accuracy of the quantitative process was also checked via inductively coupled plasma mass spectrometry. Finally, the detection limit of the method was investigated up to μg/g. The obvious advantage of the reported method was facile and reliable to achieve comprehensive identification from the dimension scale and crystal form to the component. Moreover, this analytical strategy could be also applied for the detection of other nanoscale metals or metal oxides in functional textiles.
