“…Metal oxide nanomaterials such as ZnO [1], TiO 2 [2], and Fe 3 O 4 [3] had been widely used in functional devices and biomedical applications. Among these metal oxide nanomaterials, ZnO-nanoclusters (ZnO NCs) are widely used in the fields of photoelectric materials, antibacterial agents, catalysts, coatings, and cosmetics [4][5][6][7][8]. The traditional chemical synthesis method usually uses abundant toxic, harmful reductants or stabilizers, in most cases, which are prone to cause ecological risks or irreversible environmental pollution.…”

ZnO nanoclusters (ZnO NCs) had been widely utilized in optoelectronics, sensors, dye removal, and antibacterial fields. To reduce or avoid the use of toxic, harmful, and costly chemical reagents, the Sorbus pohuashanensis and Aronia melanocarpa extracts were used to green synthesize ZnO NCs with superior adsorption ability for the organic dyes. The obtained ZnO NCs were characterized by UV–vis spectroscopy (UV–vis), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), x-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). TEM and SEM results indicated that the ZnO NCs tended to aggregate into large branching and sheet structures. EDS measurement confirmed the presence of zinc ions on the ZnO NCs. FTIR results revealed that the components of the fruits extracts were bounded on the surface of ZnO NCs. The primary application experiments demonstrated that the Sorbus pohuashanensis and Aronia melanocarpa extracts functionalized ZnO NCs possess effectively removing activity for organic dyes.

Fabricating Antibacterial Polyethylene Terephthalate Substrates Through an Industrial Approach by Applying Emulsions of Copper-Based Nanoparticles

et al. 2023

In this research, various emulsions of copper-based nanoparticles were synthesized through the chemical reduction method followed by utilizing the pad–dry–cure technique as an industrial approach to manufacturing bactericidal polyethylene terephthalate (PET) substrates. Copper sulfate/copper acetate, sodium hypophosphite (SHP)/ascorbic acid, and cetyltrimethylammonium bromide were employed as salts, reducing agents, and stabilizers, respectively. Also, a spin finish oil was used for forming an emulsion. The effects of type and amount of copper salt and reductant as well as the use of resin and stabilizer were investigated concerning antibacterial activities, weight, and color changes of coated samples to find optimum formulation. Field-emission scanning electron microscope (FESEM) images, mapping/energy-dispersive spectroscopy (EDX), X-ray diffraction (XRD) pattern, Raman spectroscopy, and UV–visible spectrophotometer was proved successful in synthesis and loading of copper-based emulsions on the PET substrates. The results revealed that change of copper salt, substituting SHP with ascorbic acid, the addition of resin, and the use of surfactant yielded negligible effect, enhancing impact, reducing the influence, and improving efficacy on bactericidal characteristics of the treated samples, respectively. Based on findings, the samples coated by emulsion containing only copper sulfate/SHP and emulsion including only copper acetate were considered optimum samples indicating 100% bactericidal properties against both S. aureus and E. coli pathogenic bacteria. Despite showing bactericidal activities, it was further found that the treated samples exhibited cell toxicity toward human skin cells implying their applications in indirect contact usages. Coated samples further indicated a good washing fastness even after 20 washing cycles. This route can be considered as a facile industrially applicable method for imparting bactericidal properties to polymeric substrates. Furthermore, such emulsions can potentially be consumed as an antibacterial spin finish oil in melt-spinning to develop antibacterial textiles.
