“…Figure 5a shows that most of the ZnO NPs were formed uniformly and possess plate‐type morphology. Moreover, due to high‐density growth, some agglomerations in the NPs were also seen 5,48 . A plate‐type morphology shows the feasibility of synthesized nanostructure for photocatalytic applications 49,50 .…”

“…The process parameters can be adjusted and optimized to tailor the NP characteristics according to specific applications. Furthermore, the hydrothermal method offers inherent advantages in terms of safety and environmental impact, as it typically uses water as the solvent and operates at relatively lower temperatures compared to other high‐temperature synthesis methods 3–5 . ZnO NPs are currently regarded as advantageous metal oxide nanoparticles (MONPs) due to their improved biocompatibility and decreased toxicity.…”

As nanotechnology gains popularity in medicine, there is a growing concern that small nanoparticles (NPs) could accumulate and penetrate deep into the human body, posing potential risks to various organs. To ensure safe usage and assess potential hazards, it is crucial to conduct a toxicological evaluation of ZnO NPs on human organs such as the kidney. The present study involved the synthesis of ZnO NPs by using the hydrothermal method. Pure and crystalline phase was confirmed by X‐ray diffraction (XRD). The SEM images displayed less agglomerated surface morphology, implying that the NPs were distributed relatively evenly and exhibited a plate‐like shape. Two pathogenic fungi Fusarium incarnatum and Aspergillus niger were isolated from the capsicum and tomato, respectively, and identified through morphological and molecular analysis. The antimycotic property of synthesized ZnO NPs were examined against Fusariumincarnatum (MT682502) and Aspergillus niger (MT675916) and showed decreased microbial growth after 9 days of incubation. The toxicological evaluation of ZnO NPs on a human embryonic kidney (HEK293) cell line showed 88% cell viability with 10 μg/ml, leading to the safe use of ZnO NPs.

“…Different physicochemical methods characterize the synthesized NPs to ascertain their distinctive characteristics, such as shape, particle size, purity, composition, surface charge, and active functional groups. These methods include Ultraviolet-Visible (UV-Vis) spectroscopy, Fourier Transform Infrared (FTIR) spectroscopy, X-Ray Diffraction (XRD), Dynamic Light Scattering (DLS), Scanning Electron and Transmission Electron Microscopy (Faridvand et al, 2021;Nayeri et al, 2021;Thakur et al, 2022). Furthermore, several factors, like temperature, pH, reaction period and precursor concentration, are essential for determining the production rate, yield, and morphologies of NPs.…”

Zinc oxide nanoparticles (ZnO-NPs) synthesized through biogenic methods have gained significant attention due to their unique properties and potential applications in various biological fields. Unlike chemical and physical approaches that may lead to environmental pollution, biogenic synthesis offers a greener alternative, minimizing hazardous environmental impacts. During biogenic synthesis, metabolites present in the biotic sources (like plants and microbes) serve as bio-reductants and bio-stabilizers. Among the biotic sources, microbes have emerged as a promising option for ZnO-NPs synthesis due to their numerous advantages, such as being environmentally friendly, non-toxic, biodegradable, and biocompatible. Various microbes like bacteria, actinomycetes, fungi, and yeast can be employed to synthesize ZnO-NPs. The synthesis can occur either intracellularly, within the microbial cells, or extracellularly, using proteins, enzymes, and other biomolecules secreted by the microbes. The main key advantage of biogenic synthesis is manipulating the reaction conditions to optimize the preferred shape and size of the ZnO-NPs. This control over the synthesis process allows tailoring the NPs for specific applications in various fields, including medicine, agriculture, environmental remediation, and more. Some potential applications include drug delivery systems, antibacterial agents, bioimaging, biosensors, and nano-fertilizers for improved crop growth. While the green synthesis of ZnO-NPs through microbes offers numerous benefits, it is essential to assess their toxicological effects, a critical aspect that requires thorough investigation to ensure their safe use in various applications. Overall, the presented review highlights the mechanism of biogenic synthesis of ZnO-NPs using microbes and their exploration of potential applications while emphasizing the importance of studying their toxicological effects to ensure a viable and environmentally friendly green strategy.

Nanoparticles are becoming integral components in every sector considering their unmatched properties with their counter bulk material. However, in the last couple of decades, several reports suggested metal nanoparticles are toxic to biological systems either directly or indirectly. Zinc oxide nanoparticles (ZnO NPs) possess excellent optical, electrical, food packaging properties, etc. Although, the use of chemically toxic reducing agents for the synthesis of ZnO NPs induces toxicity. Therefore, biogenic synthesis of ZnO NPs has been exploited using different sources such as plant leaves, stems, fungi algae, etc NPs synthesised via these methods are biodegradable, biocompatible, low toxic, and highly effective in different applications. Algae being widely available and easy to harvest becomes a suitable candidate for ZnO NPs synthesis. Algae mediated/phycosynthesis is a technique where algae accumulate zinc oxides and reduce them to zinc ions to form ZnO NPs. The ease of synthesis of ZnO NPs using this method produces NPs in abundant quantity and of variable sizes. Intracellular and extracellular syntheses are two mechanisms of phycosynthesis of ZnO NPs. These ZnO NPs have several beneficial properties like antimicrobial, anti-cancerous, antioxidant, larvicidal, antidiabetic, etc. Additionally, it has low scale-up cost, and low energy input. This article provides detailed information about the routes of phycosynthesis of ZnO NPs using different algal strains, properties, and their potential application in the biomedical field and environmental remediation.
