“…Our results are in harmony with Ruddaraju et al [50]. The results were in agreement with Ruddaraju et al and Javed et al [50,51]. The SEM images described surface topological details of different nano-objects based on the electron density of the surface due to their higher resolution and bigger field depth [52].…”

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.

“…As for composites based on modified adhesives, the authors [ 75 ] describe their anti- caries effect from two positions: (1) preventing the development of recurrent caries on teeth previously treated for it by affecting the structural elements of dentin; (2) reduction in the number of cariogenic bacteria such as S. mutans and L. acidophilus .…”

“…The antimicrobial activity of nanoparticles based on ZnO NPs and ZnO NPs encapsulated in chitosan against microorganisms B. subtilis, S. aureus, S. hemoliticus, P. aeruginosa, K. pneumoniae, E. coli was studied (Table 3). S. mutans and L. acidophilus biofilm inhibition was tested using 3M ESPE Adper™ Single Bond Adhesive dental adhesive disks containing nanoparticles [75]. It should be mentioned that ZnO NPs with chitosan showed stronger antimicrobial activity than without the polymer.…”

This review aims to describe and critically analyze studies published over the past four years on the application of polymeric dental nanomaterials as antimicrobial materials in various fields of dentistry. Nanoparticles are promising antimicrobial additives to restoration materials. According to published data, composites based on silver nanoparticles, zinc(II), titanium(IV), magnesium(II), and copper(II) oxide nanoparticles, chitosan nanoparticles, calcium phosphate or fluoride nanoparticles, and nanodiamonds can be used in dental therapy and endodontics. Composites with nanoparticles of hydroxyapatite and bioactive glass proved to be of low efficiency for application in these fields. The materials applicable in orthodontics include nanodiamonds, silver nanoparticles, titanium(IV) and zinc(II) oxide nanoparticles, bioactive glass, and yttrium(III) fluoride nanoparticles. Composites of silver nanoparticles and zinc(II) oxide nanoparticles are used in periodontics, and nanodiamonds and silver, chitosan, and titanium(IV) oxide nanoparticles are employed in dental implantology and dental prosthetics. Composites based on titanium(IV) oxide can also be utilized in maxillofacial surgery to manufacture prostheses. Composites with copper(II) oxide nanoparticles and halloysite nanotubes are promising materials in the field of denture prosthetics. Composites with calcium(II) fluoride or phosphate nanoparticles can be used in therapeutic dentistry for tooth restoration.

“…Among several metal oxide nanocomposites, ZnO nanocomposites are the most leading materials of current developments with superior properties such as biological, mechanical, optical, and electrochemical properties (Najm, 2021;Yang et al, 2021;Rajkumar and Sarma, 2021;Tariq et al, 2021). In particular, ZnO nanocomposites have been fabricated using different methods such as wet chemical, sonication, and microwave methods to obtain uniform nanomaterials (Wagener et al, 2011;Priya et al, 2020;Javed et al, 2020). Considering biopolymer blends have been used as attractive matrixes in several applications with different advantages such as biodegradability, biocompatibility, antimicrobial, antifungal, low-cost, and good transparency.…”

Recent developments have been focused on the fabrication and application of metal-metal oxide nanocomposites coated steel foam for nanomaterials, which can have excellent surface morphology and mechanical properties than conventional materials. In this study, a novel 3 dimensional (3D) biopolymer blend-ZnO nanocomposites coated Cu-Ni-Mo-based steel foam was designed and prepared. The objective of this work was to investigate the deposition of the nanofilm by immersion of the steel foam into a solution containing ZnO nanostructures and to determine the effect of the surface coating of biopolymer blend-ZnO nanocomposites onto the Cu-Ni-Mo-based steel foam. A low-cost and easy-to-use dip-coating method was preferred to obtain uniform and high quality coating layers. With this approach, the nanocoatings were prepared at 25 °C and low contact time (≈10 min). X-ray diffraction (XRD), scanning electron microscopy (SEM), and stereo microscope analysis methods were used to demonstrate surface and chemical properties of the tragacanth gum / chitosan blend encapsulated ZnO nanocomposites (TG/CH/ZnO NPs) coated Cu-Ni-Mo based steel foam. According to the SEM and stereo microscope images, the prepared 3D random shape with irregular ZnO NPs on the surface of the Cu-Ni-Mo based steel foam were formed. Furthermore, the mean surface roughness values of uncoated steel foam and TG/CH/ZnO NPs coated steel foam were measured as 4.48 µm and 4.61 µm, respectively. Additionally, the RGB pixel of the SEM micrograph of the coated steel foam was analyzed to investigate the effect of coating materials on the surface. Due to cost-efficient and green fabrication of the nanocoating, it has a significant potential to be a promising nanomaterial in biomedical applications.
