“…Moreover, they are a comparatively safe and inexpensive material that can be directly used for biomedical applications [ 23 ]. Due to these excellent properties of ZnO nanoparticles, much effort has been directed to the fabrication of ZnO with interesting morphologies and assemblies [ 24 , 25 , 26 ]. Furthermore, various methods are also used to apply ZnO nanostructures on textile materials, such as the hydrothermal route [ 27 ], ultrasonic irradiation technique, layer-by-layer deposition, pad-dry procedure, and sol–gel process [ 28 , 29 , 30 ].…”

The goal of this research is to develop a functional textile with better mechanical properties. Therefore, nano ZnO is synthesized, characterized, and applied to cotton fabric by mechanical thermo-fixation techniques. The synthesized nanoparticles are characterized by SEM and XRD analysis. The ZnO nanoparticle alone, ZnO nanoparticle with a binder, and ZnO with a binder and wax emulsion are then applied on cotton woven fabrics using three different recipes. The surface morphology of the treated fabric is studied using SEM and EDS. Antimicrobial activity, UV protection property, and crease resistance are all tested for their functional characteristics. In addition, all vital mechanical characteristics are assessed. The results suggest that using only nano ZnO or nano ZnO with a binder enhances functional features while deteriorating mechanical capabilities. Nano ZnO treatment with the third recipe, which includes the addition of an emulsion, on the other hand, significantly enhances mechanical and functional characteristics. Consequently, this study provides information to optimize the confidence of textile researchers and producers in using nano ZnO and understanding its features in key functional fabrics.

“…Furthermore, the enhancement of unique morphology and chemical properties of the green bio-nanocomposites has been reported, as well as their biodegradability, antimicrobial properties, and mechanical and thermal properties for food packaging and cosmetic applications (Scaffaro et al 2017 ; Murali et al 2019 ). Bio-nanocomposites have significant biological activity due to their uniform size distribution, homogeneous dispersion, and nanoscale sizes, ranging from 1 to 1000 nm in diameter (Nguyen et al 2021 ; Sahoo et al 2021 ). According to scientific trends, several previous studies have highlighted the antimicrobial mechanism of action of synthesized green and low-cost bio-nanocomposites (Othman et al 2021 ; Moghadam et al 2021 ; Kumaravel et al 2021 ; Shahvalizadeh et al 2021 ).…”

Nguyen et al investigated the antimicrobial activity of chitosan/ZnO bio-nanocomposites prepared via a green process using orange peel extract as a reducing agent (Nguyen et al 2021 ). Abduraimova et al showed that a synthesized cetyltrimethylammonium bromide (CTAB)-loaded SiO 2 –silver mesoporous nanocomposite was an efficient antibacterial agent which exhibited antimicrobial properties against Gram-negative and Gram-positive bacterial strains (Abduraimova et al 2021 ).…”

Currently, researchers are focusing on the development of nano-additive preservatives during the worldwide COVID-19 pandemic. This research aimed to constitute a small sized preservative nano-formulation which emerges from the biopolymer carboxymethyl cellulose (a green stabilizing agent) and hydromagnesite stromatolite (a fossilized natural additive). In this study, we investigated the optimization of the experimental design of carboxymethyl cellulose/hydromagnesite stromatolite (CMC/HS) bio-nanocomposites using a green and one-step sonochemical method at room temperature. In addition, we constructed a mathematical model which relates the intrinsic viscosity with all operating variables, and we carried out statistical error analysis to assess the validity of the proposed model. The characterization and chemical functional groups of CMC/HS bio-nanocomposites were determined by different advanced techniques such as SEM, HRTEM, DLS, FTIR, XRD, and BET. The challenge test was used to show the preservative efficacy of CMC/HS bio-nanocomposites against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Candida albicans, and Aspergillus brasiliensis. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltrazolium bromide (MTT) assay was performed on L929 cells to evaluate the in vitro cytotoxicity of CMC/HS bio-nanocomposites. According to the results, we showed that the synthesized CMC/HS bio-nanocomposites have no cytototoxic effects on L929 fibroblast cells and could be considered to be an alternative green nano-additive preservative against pathogenic microorganisms.

The innovation of facile, efficient and mild procedures utilizing contemptible, conveniently separable and reusablesolid catalysts that overcome obstacles are invariably in demand. Hence, a straightforward one-pot multicomponent reaction (MCR) and an expedient procedure for the synthesis of pyran annulated heterocycles 5 a-k and 6 l-v is developed using Chitosan-Zinc oxide (CS-ZnO) hybrid nanocatalyst. Use of aqueous medium is one of the major highlight of the present protocol. This protocol renders ease of operation, facile work up and magnified yields (90-95 %) as well as explores the use of modified polymeric substrates in the organic synthesis.
