“…The antibacterial activity of the Ag-titania fabric composite against Escherichia coli (gram-negative) and Staphylococcus aureus (gram-positive) cultures was also reviewed. EI-Rafie reported that as low as 54 ppm nanosilver for cotton textile was sufficient for effective antimicrobial finishing [11]. The efficiency of the antibacterial finish on such textile was 97 and 91 % for Staphylococcus aureus and Escherichia coli, respectively.…”

In the last few decades, people have become more concerned about their health, hygiene, lifestyle, fashion, comfort, luxury, and wellbeing. Those belonging to economically well-off sections are more often choosing to buy luxurious textiles, not only to exhibit their high social and well-off strata, but also from the compulsion in health and hygienic necessity of the present day. In the production of luxurious textiles, natural fibres like cotton, silk and wool, and man-made fibres, like polyester, acrylic and regenerated rayon (viscose) play important roles. Recently, due to the rapid growth of nanoscience and technology, various organic and inorganic nanoparticles, such as silver (Ag), TiO 2 , ZnO, SiO 2 , lignin, and Chitosan have been applied to impart attributes needed for health and hygiene, UV protection, self-cleaned, and skin-care functionalities, both in natural and synthetic textiles. Similarly, various plant molecules, biomaterials and bio-polymers, such as banana pseudostem sap (BPS), grape and mulberry fruit extracts, natural dyes, Chitosan, tulsi, silk-sericin, aloe Vera, honey, almonds, cucumber, and mint have been applied in textiles for improvement in antimicrobial, UV-protective, antioxidant, skin-nourishing, and hydrophilic properties. Natural extracts of jasmine, lavender, Champa sandalwood and such others containing active ingredients like santalols, fusanol, santene, teresantol, benzyl acetate, linalool, linalyl acetate, and benzyl benzoate have also been added in textiles for their mind-refreshing fragrance and for skin nourishing, smoothening of facial lines/wrinkles and providing impetus to immune, nervous, and brain psychological system. The requirement of various attributes for professional clothing like wrinkle-resistance, comfort and self-cleaning of fabric surface have been incorporated in textiles to develop

“…Smart textiles are one of the most promising application fields where antimicrobial nanostructures, frequently referred as nano‐antimicrobials , can be proficiently used as high performing nano‐reservoirs, providing a controlled release of bioactive non‐conventional inorganic species . The development of new antimicrobial fabrics is receiving great attention, because of the growing need for optimal hygienic conditions and specific devices that can help preventing the spread of many pandemic diseases .…”

“…The development of new antimicrobial fabrics is receiving great attention, because of the growing need for optimal hygienic conditions and specific devices that can help preventing the spread of many pandemic diseases . Various types of antimicrobial agents are generally used to limit or eliminate phenomena of textile degradation (color loss or fibers deterioration), unpleasant odors, and especially the growth of pathogenic microorganisms . In general, when let in contact with the human body, both natural and synthetic fibers can constitute an ideal environment for microbial growth.…”

“…One of the first examples reported in the literature deals with the modification of this type of material with AgNPs, the latter prepared using the sol‐gel technique . Many other methods, both chemical and physical, however, have been used for the controlled modification of natural textile fibers with Ag . In addition, the possibility of combining the antimicrobial treatment through Ag and CuNPs with the traditional finishing processes of natural fibers and leathers was also explored in the last 5 years …”

Colloids of antimicrobial metal and metal oxide nanoparticles (NPs) were electrochemically prepared and then used as surface modifiers for industrial batches of textiles. Different surface loadings could be easily deposited on the surface of the products of interest in order to inhibit the growth of microbes such as bacteria. Surface chemical characterization was performed using X-ray Photoelectron Spectroscopy technique to quantitatively assess the materials' surface chemical composition. Moreover, the NP chemical speciation was evaluated and correlated to the electrosynthesis characteristics, processing conditions, and textiles storage time. Atomic absorption spectroscopy was employed to quantify the metal ions release in a proper contact solution in order to correlate the surface and bulk availability of NPs with the antimicrobial efficacy. Promising spectroscopic results strongly support future real-life applications in different fields

There is a growing field of research on the physicochemical properties of bimetallic nanoparticles (BMNPs) and their potential use in different applications. Meanwhile, their antimicrobial activity is scarcely reported, although BMNPs can potentially achieve unique chemical transformations and synergetic effects can be presented. Towards this direction a reproducible simple hybrid polyol process under moderate temperature solvothermal conditions has been applied for the isolation of non-oxide contaminated bimetallic CuFe nanoparticles (NPs). 1,2-propylene glycol (PG), tetraethylene glycol (TEG) and polyethylene glycol (PEG 8000), that exhibit different physicochemical properties, have been utilized to regulate the size, structure, composition and the surface chemistry of NPs. The BMNPs were found to be of small crystalline size, 30-45nm, and high hydrophilicity, different wt% percentage of organic coating and variable hydrodynamic size and surface charge. The antimicrobial activity of the BMNPs was evaluated against the bacterial strains B. subtilis, E. coli and fungus S. cerevisiae. The IC values for CuFe NPs were found significantly lower compared with Cu NPs of the same size, revealing an enhancement in the antimicrobial activity when iron and copper coexist in the crystal structure. The reactive oxygen species (ROS) production was measured intracellularly and extracellularly by the nitroblue tetrazolium assay in the fungal cultures. No extracellular ROS were measured suggesting that both CuFe and Cu NPs enter the fungal cells during the incubation, also verified by optical imaging of the fungal cells in the presence of NPs. Higher ROS concentrations were generated intracellularly for CuFe NPs supporting different red/ox reaction mechanisms.
