Seeds are facing harsher environments due to the changing climate. Improving seeds' stress resilience is critical reduce yield loss. Here, we propose that using ROS-generating nanoparticles (NPs) prestimulate seeds would enhance of and seedlings through triggering stress/immune responses. We examined this hypothesis by exposing AgNPs-primed rice (Oryza sativa L.) under salt conditions (NaCl). The results showed primed exhibit accelerated germination speed, increased seedling vigor (from 22.5 47.6), biomass (11%), root length (83%) compared with hydropriming treatment. Multiomics (metabolomics transcriptomics) analyses reveal AgNPs-priming triggered metabolic transcriptional reprogramming in seeds. Signaling metabolites, such as salicylic acid, niacinamide, glycerol-3-phosphate, dramatically upon AgNPs-priming. KEGG pathway analysis reveals activated signaling defense related pathways, plant hormone signal transduction, glutathione metabolism, flavone flavonol biosynthesis, MAPK pathway, plant-pathogen interaction. These changes indicate More importantly, "stress memory" can last weeks, providing protection against blast fungus (Magnaporthe oryzae). Overall, show prestimulated AgNPs not only enable faster better conditions, but also increase resistance biotic abiotic stresses. This simple nanobiostimulant-based strategy may contribute sustainable agriculture maintaining agricultural production reducing use pesticides.

While great progress in nanozyme-enabled analytical chemistry has been made, most current nanozyme-based biosensing platforms are based on peroxidase-like nanozymes. However, nanozymes with multienzymatic activities can influence the detection sensitivity and accuracy, while use of unstable hydrogen peroxide (H2O2) a catalytic reaction may result reproducibility challenge sensing signals. We envision that constructing systems by using oxidase-like address these limitations. Herein, we reported platinum–nickel nanoparticles (Pt–Ni NPs) Pt-rich shells Ni-rich cores possessed high efficiency, exhibiting 2.18-fold higher maximal velocity (vmax) than initial pure Pt NPs. The Pt–Ni NPs were applied to develop colorimetric assay for determination total antioxidant capacity (TAC). levels four bioactive small molecules, two nanomaterials, three cells successfully measured.

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 N2 as critical ecosystem service. BNF can be severely compromised by abiotic stresses. Enhancing increasingly important not only alleviate food insecurity but also reduce the environmental impact agriculture decreasing chemical fertilizer inputs. However, this proven challenging using current genetic modification or bacterial nodulation methods. Here, we demonstrate that single application dose (10 mg/kg) molybdenum disulfide nanoparticles (MoS2 NPs) enhance soybean grain yield 30%, compared with conventional molybdate fertilizer. Unlike molybdate, MoS2 NPs more sustainably release Mo, then effectively incorporated cofactor for synthesis nitrogenase molybdenum-based enzymes subsequently BNF.
