“…Silver nanoparticles (AgNPs) have a broad-spectrum antibacterial activity against Gram positive and Gram-negative bacteria such as S. aureus and E. coli [ [14] , [15] , [16] , [17] ]. Silver ions are linked to the bacterial cell wall and interact with the thiol groups in enzymes and proteins, causing inhibition of bacterial growth and deposited in the vacuole and cell wall as granules which leads to bacterial cell death [ 18 , 19 ]. Recently, the antimicrobial activity of silver nanoparticles against numerous viruses such as HIV-1, hepatitis, respiratory syncytial, herpes simplex, monkeypox and H 1 N 1 influenza A have been investigated.…”

“…The incorporation of metal nanoparticles in polymer composites has been investigated in several studies because of their distinctive properties. Glucose is utilized in reducing silver nitrate into silver nanoparticles in the presence of polyvinyl alcohol (PVA), which reacts as a good host material for metal and semiconductor due to its good thermal stability and chemical resistance [ 18 , 28 ]. PVA is a green and ecofriendly biopolymer because of its water solubility, biocompatibility and non-toxicity, so it is widely used in various biomedical applications [ [29] , [30] , [31] , [32] , [33] ].…”

Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). We succeeded in preparing disinfectant cellulose-based wipes treated with antimicrobial and antiviral silver nanoparticles to be used for prevention of contamination and transmission of several pathogenic viruses and microbes to human in critical areas such as hospitals and healthcare centers especially coronavirus. In this work, the antimicrobial and antiviral activities of silver nanoparticles (AgNPs) prepared with four different techniques were investigated for the utilization as a disinfectant for cellulose-based wipes. These four methods are namely; 1) trisodium citrate with cotton yarn as a reducing agent, 2) preparing AgNP's using aqueous solution of PVA in the presence of glucose, 3) trisodium citrate with cotton fabric as a reducing agent, and 4) photochemical reaction of polyacrylic acid and silver nitrate solution. Polyester/viscose blended spunlace nonwoven fabrics as cellulose based fabrics were treated with the prepared silver nanoparticles to be used as surfaces disinfection wipes. The properties of the nonwoven fabrics were examined including thickness, tensile strength in dry and wet conditions in both machine direction (MD) and cross-machine direction (CMD), bursting strength, air permeability, water permeability and surface wettability. Characterization of the AgNPs was carried out in terms of UV-VIS spectroscopy, TEM, SEM, and Zeta potential analysis. The assessment of AgNPs active solutions for antimicrobial and antiviral activities was evaluated. The results obtained from the analyses of the AgNPs samples prepared with different techniques showed good uniformity and stability of the particles, as well uniform coating of the AgNPs on the fibers. Additionally, there is a significant effect of the AgNPs preparation method on their disinfectant performance that proved its effectiveness against coronavirus (MERS-CoV), S. aureus and B. subtilis as Gram-positive bacteria, E. coli and P. mirabilis as Gram-negative bacteria, A. niger and C. albicans fungi.

“…Cotton fibres are inherently nutritious and hydrophilic and therefore provide an excellent environment for the growth of bacteria and fungi (Ravindra et al 2010), and they do not in themselves have an effective barrier to UV radiation, especially when undyed or dyed in light shades (Czajkowski and Paluszkiewicz 2008). Silver nanoparticles (AgNP) applied on cotton have been found to play an important role in developing protective properties against pathogenic bacteria (Bachir and Abouni 2015;Ibrahim et al 2020;Khalil et al 2014; Barani and Mahltig 2020) and UV radiation (Rao et al 2019;Aladpoosh et al 2014). The application of AgNP on cotton fabrics can be carried out in two-step or one-step processes.…”

The development of cellulose-based textiles that are functionalised with silver nanoparticles (AgNP), synthesised according to a green approach, and offer protection against ultraviolet (UV) radiation and pathogenic bacteria is very important today. In the present work we demonstrate the environmentally friendly approach to obtain such textile material by AgNP synthesis directly (in-situ) on cotton fabrics, using water extracts of plant food waste (green tea leaves, avocado seed and pomegranate peel) and alien invasive plants (Japanese knotweed rhizome, goldenrod flowers and staghorn sumac fruit) as reducing agents. The extracts were analysed for their total content of phenols and flavonoids and their antioxidant activity. The synthesised AgNP on cotton were round, of different size and amount depending on the reducing agent used. The highest amount of AgNP was found for samples where Japanese knotweed rhizome extract was used as reducing agent and the lowest where extracts of goldenrod flowers and green tea leaves were used. Regardless of the reducing agent used to form AgNP, all cotton samples showed excellent protection against E. coli and S. aureus bacteria and against UV radiation with UV protection factor values above 50. The best results for UV protection even after the twelve repetitive washing cycles were found for the sample functionalized with AgNP synthesised with an extract of the Japanese knotweed rhizome. Due to the presence of AgNP on cotton, the air permeability and thermal conductivity decreased. AgNP had no effect on the change in breaking strength or elongation of fabrics. Graphic abstract

“…In addition, the leaf of MO has antimicrobial, antioxidative, antifungal properties. Some studies, MO leaf extracts has been used to coat the textile fabrics in medical field [8] , [9] . Likewise, curcumin is a pigment which is existing in the turmeric, it has been used for centuries as a major food ingredient /additive and for skin care, owing to their anti-inflammatory, antifungal, antitumor activities, as well as a cancer chemo-preventive agent [5] , [6] .…”

As the epidemic of coronavirus disease (COVID-19) has spread rapidly, health organizations around the world has made wearing face mask obligatory to prevent the spread of the infections for the wellness of the society. As wearing face masks become a daily routine, the usage of cloth facemasks from textile fabric, is popular among the public. Since antiquity, textiles have been proven to be intertwined with human lives and the integrant of these crucial materials are fibers. Particularly, nanofiber fabrics manufactured by electrospinning have attracted attention, owing to the better filtration efficiency and breathability. In addition, the electrospinning process provide opportunities to fine tuning of the surface functionality through polymer chemistry and an encapsulation of bioactive agents in single step process. This review opens up a new horizon in possible textile applications especially, an active layer of bioactive agent (Curcumin and Moringa) loaded nanofibrous fabrics-based facemasks for day to day life.
