“…As an alternative to underused agricultural biochemical products, antifungal hybrid materials based on lignin as a biomass feedstock are widely accessible for the production of nanoparticles. Certainly, the utilization of a green and biodegradable polymer, such as lignin/n-lignin, as a stabilizer and reducing agent showcases its minimal environmental impact, as evidenced by a much lower silver ion release or even the absence of silver ion release after the implementation ability to inhibit microbial growth. , The targeted biosubstrate nanoparticles will rapidly lose their postutilization activity and biodegrade in the environment after disposal…”

Aspergillus flavus (A. flavus) and Aspergillus niger (A. niger) mainly spread through airborne fungal spores. An effective control to impede the dissemination of the spores of Aspergillus in the air affecting the environment and food was carried out. This study focuses on the sustainable rice husk-extracted lignin, nanolignin, lignin/n-lignin capped silver nanoparticles used for fungal growth inhibition. These biomaterials inhibit the growth of fungi by altering the permeability of cell membranes and influencing intracellular biosynthesis. The antifungal indexes for A. flavus and A. niger on day 5 at a concentration of 2000 μg/100 μL are 50.8 and 43.6%, respectively. The results demonstrate that the hybrid biomaterials effectively prevent the growth or generation of fungal spores. The findings of this research hold significant implications for future investigations focused on mitigating the dissemination of Aspergillus during the cultivation of agricultural products or in the process of assuring agricultural product management, such as peanuts and onions.

“…Several metal oxide nanoparticles have been reported for their potential antibacterial activities against Gramnegative and Gram-positive bacteria, consisting of Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. These metal oxide nanoparticles include Al 2 O 3 (Jawad et al 2021;Karimi et al 2021), CuO, Cu 2 O, ZnO (Asamoah et al 2020;Karuppannan et al 2021;Han et al 2022;Khosravi et al 2022), CaO (Abbas and Aadim 2022), MnO 2 , MgO (Ogunyemi et al 2020;Amrulloh et al 2021), TiO 2 (Wang et al 2020;Zhang et al 2021), Fe 3 O 4 (Azizabadi et al 2021;Kamali et al 2022), Ag 2 O (Rashidi Ranjbar et al 2020;Dharmaraj et al 2021;Mahlambi and Moloto 2022), NiO (Kannan et al 2020;Christy et al 2021), and SiO 2 (Attallah et al 2022;Tran et al 2023). The antibacterial activity lies in its physical and chemical properties, which include morphology, chemical composition, particle size, surface characteristics, solubility, crystallinity, aggregation, and crystal phase.…”

This study aimed to compare the spectroscopy, morphological, electrocatalytic properties, and antibacterial activities of cobalt nanoparticles (CoNPs) with nickel nanoparticles (NiNPs). Cobalt nanoparticles and NiNPs were prepared via a chemical reduction approach and characterized utilizing transmission electron microscopy (TEM), energy-dispersive X-ray (EDX), and X-ray diffraction (XRD) techniques. The result from XRD and TEM analysis revealed that the synthesized nanoparticles exhibit face-centered cubic with smooth spherical shape, having average particles size of 12 nm (NiNPs) and 18 nm (CoNPs). The electrochemical properties of the nanoparticles were examined via cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) techniques. The CV results showed that GCE-Ni (35.6 μA) has a higher current response compared to GCE-Co (10.5 μA). The EIS analysis revealed that GCE-Ni (1.39 KΩ) has faster electron transport capability compared to GCE-Co (2.99 KΩ) as indicated in their Rct values. The power density of the synthesized nanoparticles was obtained from their "knee" frequency (f°) values, with GCE-Ni (3.16 Hz) having higher f° values compared to GCE-Co (2.00 Hz). The antibacterial activity of the nanoparticles was evaluated against multidrug-resistant Escherichia coli O157, Escherichia coli O177, Salmonella enterica, Staphylococcus aureus, and Vibrio cholerae. The result from the antibacterial study revealed that at low concentrations both CoNPs and NiNPs have significant antibacterial activities against E. coli O157, E. coli O177, S. enterica, S. aureus, and V. cholerae. NiNPs showed better antibacterial activities at low concentrations of 61.5, 61.5, 125, 61.5, and 125 µg/mL compared to CoNPs with minimum inhibitory concentrations of 125, 125, 250, 61.5, and 125 µg/mL against E. coli O157, E. coli O177, S. enterica, S. aureus, and V. cholerae, respectively. These promising antibacterial activities emphasize the potential of CoNPs and NiNPs as effective antibacterial agents, which could aid in the development of novel antibacterial medicines.
