“…Both the NPs release Ag 2+ /Ag1 + and Cu 2+ ions, which, as a result of electrostatic attraction, collide with the negatively surface charged bacterial cell wall and disintegrate the bacteria's protective cell wall ( Al-Enazi et al, 2023 , Ameen et al, 2023d ). Consequently, the material found inside the cell will be exposed.…”

“…Fungal mycelia grow on the surface of the anode or in the anodic chamber, releasing their degradative and fermentative enzymes. The traditional biological procedure is insufficient in pollutant remediation because of the absence of “biocatalytic activity” ( Dawoud et al, 2021 ; Al-Enazi et al, 2023a , b ). Deposited catalysts have gained significant interest at electrodes, accelerating the kinetics reaction (the electrodes).…”

“…The disadvantage is the significant cost of the enzymes, which could be improved via a technology that is recombinant DNA. Ferricyanide reductase and Lactate dehydrogenase are readable enzymes ( Prasad et al, 2007 ; Al-Enazi et al, 2023a , b ). Wood degraders secrete many extracellular enzymes, such as laccase.…”

Integrating fungi into fuel cell systems presents a promising opportunity to address environmental pollution while simultaneously generating energy. This review explores the innovative concept of constructing wetlands as fuel cells for pollutant degradation, offering a practical and eco-friendly solution to pollution challenges. Fungi possess unique capabilities in producing power, fuel, and electricity through metabolic processes, drawing significant interest for applications in remediation and degradation. Limited data exist on fungi’s ability to generate electricity during catalytic reactions involving various enzymes, especially while remediating pollutants. Certain species, such as Trametes versicolor, Ganoderma lucidum, Galactomyces reessii, Aspergillus spp., Kluyveromyce smarxianus, and Hansenula anomala, have been reported to generate electricity at 1200 mW/m3, 207 mW/m2, 1,163 mW/m3, 438 mW/m3, 850,000 mW/m3, and 2,900 mW/m3, respectively. Despite the eco-friendly potential compared to conventional methods, fungi’s role remains largely unexplored. This review delves into fungi’s exceptional potential as fuel cell catalysts, serving as anodic or cathodic agents to mitigate land, air, and water pollutants while simultaneously producing fuel and power. Applications cover a wide range of tasks, and the innovative concept of wetlands designed as fuel cells for pollutant degradation is discussed. Cost-effectiveness may vary depending on specific contexts and applications. Fungal fuel cells (FFCs) offer a versatile and innovative solution to global challenges, addressing the increasing demand for alternative bioenergy production amid population growth and expanding industrial activities. The mechanistic approach of fungal enzymes via microbial combinations and electrochemical fungal systems facilitates the oxidation of organic substrates, oxygen reduction, and ion exchange membrane orchestration of essential reactions. Fungal laccase plays a crucial role in pollutant removal and monitoring environmental contaminants. Fungal consortiums show remarkable potential in fine-tuning FFC performance, impacting both power generation and pollutant degradation. Beyond energy generation, fungal cells effectively remove pollutants. Overall, FFCs present a promising avenue to address energy needs and mitigate pollutants simultaneously.

“…The nanotechnology has exhibited a high potential in a wide range of cytology research topics such as diagnosis/sensing (Wang et al, 2021), monitoring (Laraib et al, 2022), and treatment strategies (Mohammad et al, 2023) by providing valuable ideas (Alijani et al, 2022) such as nanomachine (Mirzaiebadizi et al, 2022). As an alternate and combined treatment technology, researchers attempted to synthesis and design nanomedicines program for cancer treatment through the help of novel properties of nanostructures such as nanorods (Isacfranklin, Ameen, et al, 2020; Isacfranklin, Dawoud, et al, 2020), nanocubes (AlYahya et al, 2018), doped (Al‐Enazi et al, 2023; Rao et al, 2018), metal–organic framework (Zeng et al, 2020). The goal of novel strategies is to destroy cancer cells by the induction of apoptosis through the utilization of signaling pathways (Xue et al, 2022), which proved to be effective in controlling cancer cells by reducing the complications of healthy cells.…”

The nanostructures have the great potential for novel medical and drug delivery applications. In present paper a green approach for the preparation of pure nickel oxide (NiO) and 5% cobalt‐doped NiO (Co╫NiO) nanoparticles (NPs) by using Prosopis fracta extract have been study. The product of Co╫NiO NPs was proved through the PXRD, Raman, UV–Vis, FESEM, and EDX analyses. The results of XRD, EDX, and UV–Visible spectra displayed well doped cobalt in NiO NP. The particle sizes of Co╫NiO NPs were observed to be about 80 nm. The MTT test results for the cytotoxicity of Co╫NiO NPs on breast cancer cells (MCF‐7) affirmed the stronger impact of doped NiO‐NPs on cancer cells compared to NiO NPs. Thus, it is indicated that the doping process on NiO NPs caused an increase in its inhibitory effect against MCF‐7 cells.Research Highlights Cobalt‐doped NiO nanoparticles were prepared using ecofriendly synthesis method and their cytotoxicity studied against MCF‐7 cells.
