“…Because of the broad range of uses of zinc oxide nanoparticles (ZnONPs), such as smart UV sensors, they have piqued researchers' attention [15], targeted drug delivery [16], antioxidant activity [17] biosensors [18], environmental remediation [19] and as a drought-tolerant agent as well as nutrient supply of crops [20]. Moreover, ZnONPs are characterized to be efficient against pathogenic fungi, mostly by their antimicrobial properties according to their photo-oxidizing and photocatalytic effects and considering infection control for the plant host [21]. Recently detailed reviews introduced the preparation methods and antifungal properties of ZnONPs and their possible antifungal mechanisms for plant diseases management and to improve food quality [22,23].…”

ZnO-based nanomaterials have high antifungal effects, such as inhibition of growth and reproduction of some pathogenic fungi, such as Fusarium sp., Rhizoctonia solani and Macrophomina phaseolina. Therefore, we report the extracellular synthesis of ZnONPs using a potential fungal antagonist (Trichoderma harzianum). ZnONPs were then characterized for their size, shape, charge and composition by visual analysis, UV–visible spectrometry, X-ray diffraction (XRD), Zeta potential, transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy-dispersive X-ray analysis (EDX). The TEM test confirmed that the size of the produced ZnONPs was 8–23 nm. The green synthesized ZnONPs were characterized by Fourier transform infrared spectroscopy (FTIR) studies to reveal the functional group attributed to the formation of ZnONPs. For the first time, trichogenic ZnONPs were shown to have fungicidal action against three soil–cotton pathogenic fungi in the laboratory and greenhouse. An antifungal examination was used to evaluate the bioactivity of the mycogenic ZnONPs in addition to two chemical fungicides (Moncut and Maxim XL) against three soil-borne pathogens, including Fusarium sp., Rhizoctonia solani and Macrophomina phaseolina. The findings of this study show a novel fungicidal activity in in vitro assay for complete inhibition of fungal growth of tested plant pathogenic fungi, as well as a considerable reduction in cotton seedling disease symptoms under greenhouse conditions. The formulation of a trichogenic ZnONPs form was found to increase its antifungal effect significantly. Finally, the utilization of biocontrol agents, such as T. harzianum, could be a safe strategy for the synthesis of a medium-scale of ZnONPs and employ it for fungal disease control in cotton.

<p><span>The quality of human life is compromised due to the increased concentration of toxic heavy metals in air, water, and soil which is directly interacted with living life. Exceed levels of Cr, Cd, Cu, As, Zn, Pb, and Hg influence the living chain and not only causes human damage but also greatly effects animals, plants, and microorganisms. The consistent increase in drawbacks of traditional methods makes them a poor choice for the remediation of heavy metals. In comparison to that, the use of advanced technology at nano levels gives promising results. Many nanomaterials such as carbon nanotubes, nanofibers, nanoflowers, and nanoadsorbents of different metals such as copper, titanium, zinc, gold, silver, iron, cerium, and manganese use along with different biological materials increase the nano-bioremediation rate in the field of science and pose industrial and environmental applications. Being a cost-effective, eco-friendly, controllable nature of nano-bioremediation technology, they lack background knowledge, and handling at the commercial level. This review highlights different types of nanomaterials, how they are implemented in different application, their green synthesis approach, and the boon and bane of using nano-bioremediation technology in real-time.</span></p>

“…Due to their distinctive characteristics, MONPs are beneficial in multiple dermato‐cosmetic applications [7] . Previous studies indicate that zinc oxide NPs (ZnO‐NPs) displayed several biological activities such as antimicrobial, [8] antifungal, [9] anticancer, [10] and wound healing [11] . However, the leading quality of ZnO‐NPs is incorporating them into sunscreens.…”

This research paper explores the field of nanobiotechnology, focusing on the design, characterisation, and potential dermal applications of metal oxide nanoparticles (MONPs). ZnO and FeO NPs exhibit distinctive properties that are valuable in dermato‐cosmetic applications and transdermal drug delivery. This study investigates Cannabidiol (CBD) as a capping agent for MONPs synthesis. Employing microwave‐assisted techniques, MONPs were synthesised using either CBD or polyvinylpyrrolidone (PVP) as capping agents. The TEM, SEM, FTIR, and XRD characterisation results confirmed the successful formation of CBD‐capped ZnO and FeO NPs exhibiting an average particle size of 90 and 76 nm, respectively. The cytotoxicity of CBD‐capped MONPs was evaluated on HaCaT cells over a concentration range of 100 to 6.25 μg/mL, which revealed that CBD‐capped ZnO NPs exerted a cytotoxic effect on HaCaT cells (IC50 85.34±1.17 μg/mL). In contrast, CBD‐capped FeO NPs and PVP‐capped MONPs exhibited negligible cytotoxicity (IC50 >100 μg/mL). TEM analysis revealed a noticeable structural alteration of ZnO NPs in the supplemented cell culture medium, which could contribute to enhanced NP uptake, thereby explaining the more pronounced cytotoxic effect of ZnO NPs. Therefore, the disparity in cytotoxic responses can be attributed to the protein coating adhering to the NPs surface in a biological medium.
