“…Stan et al 31 demonstrated that ZnO NPs synthesized from Allium sativum extract inhibited the growth of S. aureus, E. coli, B. subtilis, P. aeruginosa, L. monocytogenes, and S. typhimurium to a greater extent than chemically-synthesized ZnO NPs. Álvarez-Chimal et al 50 found that the inhibitory effect of ZnO NPs synthesized from Dysphania ambrosioides extract on S. aureus and S. epidermidis was equivalent to that of chlorhexidine. Ali et al 51 demonstrated that ZnO NPs synthesized from Aloe vera extract combined with antibiotics were effective at killing methicillin-resistant S. aureus (MRSA) clinical isolates.…”

In an era of environmentally friendly development, methods of the green synthesis of zinc oxide nanoparticles (ZnO NPs) from plant extracts have become a focus of research attention because of the benefits of environmental sustainability, simplicity, and low price. The present review introduces a green mechanism for the synthesis of ZnO NPs using the extracts of plants, exploring factors that influence the morphology of ZnO NPs and their antibacterial properties, and the mechanisms of antibacterial action. The results indicate that the factors that influence morphology include the intrinsic crystallographic morphological properties and conditions of the preparation of ZnO NPs. In terms of preparation conditions, the influence of plant extract concentration, precursor concentration, reaction time, and calcination temperature on NP morphology is related to the species of plants used, with precursor concentration the most significant factor affecting the morphology of ZnO NPs. A pH of 12 appears be the most appropriate alkalinity for the synthesis of ZnO NPs from plant extracts. In addition, the synthesized ZnO NPs display excellent antibacterial properties, the mechanism of which involves photocatalysis, reactive oxygen species, and interactions between ZnO NPs and bacterial surfaces. Factors influencing the antibacterial properties are the type of bacteria and the concentration and morphology of ZnO NPs. Finally, the methods of preparation of antibacterial textiles using synthetic ZnO NPs are discussed in relation to the preparation of antibacterial fibers, fabric, and composite textiles. Here, the future trend of such antibacterial textiles is considered, providing the direction for further research of antibacterial textiles.

“…The antimicrobial activity of green synthesized ZnO nanoparticles from the extract of Acacia caesia (L.) Willd. was tested using the agar well diffusion method [99]. The human pathogenic microorganisms used in this study included two bacterial strains (Escherichia coli ATCC 25922 and Staphylococcus aureus ATCC 25923) and two fungal strains (Aspergillus niger ATCC 16404 and Candida albicans ATCC 10231).…”

This paper presents the green synthesis and characterization of ZnO nanoparticles and their microbial and photocatalytic application. The green synthesis of ZnO nanoparticles was carried out using Zinc nitrate hexahydrate and the bark extract of Acacia caesia (L.) Willd. The nanoparticles were synthesized at an optimum temperature of 65 °C followed by calcination at 400 °C. The samples were characterized using UV-visible spectroscopy, SEM, XRD, FTIR and EDX analysis. UV-visible spectroscopy showed a characteristic peak at 338 nm and the bandgap energy was found to be 3 eV which is specific for ZnO. SEM confirmed the presence of ZnO on its nanoscale. EDX gave the elemental details of Zinc constituting to 37.77% and Oxygen comprising 20.77% of its atomic weight. XRD analysis gave the diffractogram indexed at various angles corresponding to ZnO nanoparticles. It also revealed the average crystalline size to be 32.32 nm and the shape was found to be hexagonal. The functional group present in the nanoparticles was characterized using FTIR, which gave a characteristic peak at 485 cm−1. The synthesized nanoparticles exhibited significant photocatalytic (methyl blue under UV irradiation). The presence of nanoparticles induces changes in its kinetics, whose rate constants and correlation coefficients were analyzed during the photocatalytic degradation of the model pollutant Methyl Blue. Studies on antibacterial (Escherichia coli, Staphylococcus aureus), antifungal (Aspergillus niger, Candida albicans) and anti-inflammatory (COX assay) properties were also carried out. The nanoparticles were synthesized in an eco-friendly and cost-effective method. The study opens new horizons in the field of water treatment, biosensors and nanotechnology.

“…However, plant extracts provide non-toxic and natural reducing, capping, and stabilizing agents for green synthesis of ZnO NPs ( Basnet et al, 2018 ). Many researchers have used plant extracts, such as Citrus sinensis peel extract ( Gao et al, 2020 ), Dysphania ambrosioides extract ( Álvarez-Chimal et al, 2021 ) and leaf extract of Mussaenda frondosa L ( Jayappa et al, 2020 ) to green synthesis of ZnO NPs. Except for plant extract, in the last two decades, ultrasound has been extensively used in the green synthesis of metal or metal oxide NPs because the acoustic cavitation produces sheer force, agitation, elevated temperature, and free radicals, which lead to the synthesis of smaller NPs with narrower size distribution in a shorter time period without the use of reducing agents ( Duan et al, 2015 ).…”
