“…In addition, the use of nanomaterials in the production of smart textiles imparts other important properties to fabrics, such as antibacterial properties [ 2 ], protection against UV radiation [ 3 ], and water-repellent properties [ 4 ], without altering the breathability, flexibility, lightness, and tactility of the fabrics. Smart textiles treated with nanoparticles have a wide range of applications in electronics [ 5 ], environment [ 6 ], sports [ 7 ], human reproduction [ 8 ], pharmaceuticals [ 9 ], and medicine [ 10 ].…”

With the rapid growth of electronic textiles, there is a need for highly conductive fabrics containing fewer conductive materials, allowing them to maintain flexibility, low cost and light weight. Poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS), is one of the most promising conductive materials for the production of conductive fabrics due to its excellent properties such as solubility, relatively high conductivity, and market availability. Moreover, its electrical conductivity can be enhanced by polar solvents or acid treatment. The aim of this work was to fabricate conductive cotton fabrics with a small fixed amount of PEDOT:PSS and to investigate how titanium dioxide (TiO2) nanoparticles affect the electrical, thermal and structural properties of PEDOT:PSS-coated cotton fabrics. The change in electrical conductivity of the nanocomposite fabric was then related to morphological analysis by scanning electron microscopy and X-ray diffraction. We found that the sheet resistance of the nanocomposite cotton fabric depends on the TiO2 concentration, with a minimum value of 2.68 Ω/□ at 2.92 wt% TiO2. The effect of UV light on the sheet resistance of the nanocomposite cotton fabric was also investigated; we found that UV irradiation leads to an increase in conductivity at an irradiation time of 10 min, after which the conductivity decreases with increasing irradiation time. In addition, the electrical behavior of the nanocomposite cotton fabric as a function of temperature was investigated. The nanocomposite fabrics exhibited metallic behavior at high-TiO2 concentrations of 40.20 wt% and metallic semiconducting behavior at low and medium concentrations of 11.33 and 28.50 wt%, respectively. Interestingly, cotton fabrics coated with nanocomposite possessed excellent washing durability even after seven steam washes.

“…These materials have exceptional functional, magnetic, optical, electrical, and mechanical properties (Silva, 2004). Many applications use the NPs as antimicrobial, anticancer, antioxidant and environmental remediation agents (Kakade, 2003). Some metal and metal oxide NPs showed strong antimicrobial effects against different bacterial strains including Bacillus sp., Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa (Gopinath et al, 2012;Khan & Bano, 2016a, 2016b.…”

Green synthesis sources for synthesizing metal oxide nanoparticles are an interesting and expanding research area due to their potential antibacterial applications. Generally, nanoparticles are prepared using different chemical and physical methods that yield toxic or harmful nano-scaled particles in addition to the high cost and complicated processing steps. The present study successfully biosynthesized manganese oxide nanoparticles (MnO NPs) by reducing Manganese sulfate (MnSO4.H2O) using the cell-free supernatant of Bacillus subtilis ATCC6633. The formation of MnO NPs was confirmed by UV-Vis spectroscopy, Fourier-transform infrared spectroscopy (FT-IR), Zeta analysis and transmission electron microscope (TEM). The biosynthesized MnO NPs displayed two absorption peaks at 285 and 353 nm. FT-IR spectrum proved the existence of bacterial proteins during the biosynthesis of MnO NPs that might act as stabilizing agents. MnO NPs have a negative charge of -20.4 mV according to Zeta analysis. TEM micrographs showed the rod-shape of MnO NPs with lengths of 70 to 100 nm and diameters of 10 to 23 nm. MnO NPs had a bactericidal action against Bacillus cereus and Escherichia coli with zones of inhibition of 23 and 25 mm, respectively in addition to minimum inhibitory concentration values of 20 and 15 µg/ml, respectively. The obtained results highlighted the possibility of using MnO NPs as a strong antibacterial agent in different industrial and medical applications.
