“…Notably, Mo adsorption in the grain is significantly less for MoS 2 NPs than with MoS 2 NS and Na 2 MoO 4 (Figure 2f); although Mo toxicity is usually very rare, this does suggest reduced risk for the NPs form of the element. 28 The health risk analysis further showed that Mo accumulated in soybean grains treated with 10 and 100 mg/kg MoS 2 NPs posed no health risk to humans (Table S1).…”

Soybean (Glycine max) is a crop of global significance and has low reliance on N fertilizers due to its biological nitrogen fixation (BNF) capacity, which harvests ambient N 2 as a critical ecosystem service. BNF can be severely compromised by abiotic stresses. Enhancing BNF is increasingly important not only to alleviate global food insecurity but also to reduce the environmental impact of agriculture by decreasing chemical fertilizer inputs. However, this has proven challenging using current genetic modification or bacterial nodulation methods. Here, we demonstrate that a single application of a low dose (10 mg/kg) of molybdenum disulfide nanoparticles (MoS 2 NPs) can enhance soybean BNF and grain yield by 30%, compared with conventional molybdate fertilizer. Unlike molybdate, MoS 2 NPs can more sustainably release Mo, which then is effectively incorporated as a cofactor for the synthesis of nitrogenase and molybdenum-based enzymes that subsequently enhance BNF. Sulfur is also released sustainably and incorporated into biomolecule synthesis, particularly in thiol-containing antioxidants. The superior antioxidant enzyme activity of MoS 2 NPs, together with the thiol compounds, protect the nodules from reactive oxygen species (ROS) damage, delay nodule aging, and maintain the BNF function for a longer term. The multifunctional nature of MoS 2 NPs makes them a highly effective strategy to enhance plant tolerance to abiotic stresses. Given that the physicochemical properties of nanomaterials can be readily modulated, material performance (e.g., ROS capturing capacity) can be further enhanced by several synthesis strategies. This study thus demonstrates that nanotechnology can be an efficient and sustainable approach to enhancing BNF and crop yield under abiotic stress and combating global food insecurity.

“…This reduction in silver ion release rate after the initial burst could be attributed to the MoO 3 /PAN composite membrane having functional groups that can interact with silver ions. These interactions can lead to the binding or complexation of silver ions on the membrane surface or within its structure. , This binding reduces the concentration of free silver ions available for release. Additionally, at the start, the membrane has many available binding sites for silver ions, but over time, these binding sites might be decreased, resulting in reduced release. ,, …”

“…To tackle this challenge of preventing infections of microorganisms, there has been active research in alternative antibacterial technologies that could replace conventional remedial treatment. , Unlike antiseptic drugs that attack sites within the cells, metal-containing nanomaterials possess inherent passive antibacterial mechanisms that make them less prone to resistance. These mechanisms involve direct interactions with microorganisms, the release of metal ions that generate reactive oxygen species (ROS), and the indirect enhancement of ROS production that helps to combat bacteria. ,− Moreover, these nanomaterials possess properties that can be easily modified and tailored according to needs, making them more flexible compared to antibiotics. Despite the advantages of using metal-based nanomaterials for their passive antibacterial properties, they can still have some drawbacks.…”

The development of hybrid composite antibacterial agents for wound dressing has garnered significant attention due to their remarkable antibacterial efficacy and their potential to mitigate microbial resistance. In this study, we present an approach to designing and fabricating wound dressing membranes, utilizing molybdenum oxide–polyacrylonitrile (MoO 3 /PAN) hybrid composites through electrospinning. Subsequently, we enhanced the membrane’s effectiveness by introducing silver (Ag@MoO 3 /PAN) into the matrix via a rapid (within one min) green synthesis method under UV irradiation. Initially, we discuss the morphological characteristics and structural attributes of the resulting membranes. Subsequent investigations explore the antibacterial mechanisms of both MoO 3 and Ag + , revealing that the incorporation of silver substantially enhanced antibacterial activity. Additionally, we elucidate the surface properties, noting that the introduction of silver increases the surface area of the composite membrane by 25.89% compared with the pristine MoO 3 /PAN membrane. Furthermore, we observe a 9% reduction in the water contact angle (WCA) for the Ag@MoO 3 /PAN membrane, indicating improved hydrophilicity. Finally, we analyze the release behavior of the Ag@MoO 3 /PAN membrane. Our findings demonstrate an initial burst release within the first 7 h, followed by a controlled and sustained release pattern over a period of 7 days.

Antimicrobial packing showed great potential in extending the shelf life of food. However, developing a new biocomposite film with an intelligent and efficient antimicrobial performance is still desirable. Herein, a Fe-MoO x encapsulated with curcumin (Cur) filled chitosan-based composite film (CCF films) was prepared by solvent casting method. The total color differences of the CCF films were less than 30%, and satisfactory surface color, transparency, hydrophobicity, and thermal stability were also obtained. Besides, the UV-light/water/oxygen barrier capability and mechanical properties were enhanced with the incorporation of Cur@Fe-MoO x . Moreover, CCF films showed photothermal performance and thermal-controlled curcumin release ability, which endowed the CCF 0.15 film with excellent antibacterial capability toward E. coli (≥99.95%) and S. aureus (≥99.96%) due to the synergistic antibacterial effect. Fe-MoO x exhibited high cell viability and less than 5% hemolysis even under the concentration of 500 μg mL −1 . Based on those unique characteristics, the CCF 0.15 film was chosen for tangerine preservation. The CCF 0.15 film could prolong the shelf life of tangerine by at least 9 days compared with the unpacking group, and the tangerines could maintain the freshness characteristics over a 24 day storage period. Such thermal-mediated antibacterial film proposed by our work showed promising potential in food packaging.
