Platinum–Nickel Nanoparticles with Enhanced Oxidase-like Activity for Total Antioxidant Capacity Bioassay

Analytical Chemistry, Journal Year: 2023, Volume and Issue: 95(14), P. 5937 - 5945

Published: March 27, 2023

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. Our work not only provides new insights preparing highly active but also manifests their applications TAC analysis.

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. Sulfur released into biomolecule synthesis, particularly in thiol-containing antioxidants. The superior antioxidant enzyme activity NPs, together thiol compounds, protect nodules from reactive oxygen species (ROS) damage, delay nodule aging, maintain function longer term. multifunctional nature makes them highly effective strategy plant tolerance Given physicochemical properties nanomaterials readily modulated, material performance (e.g., ROS capturing capacity) further enhanced several strategies. This study thus demonstrates nanotechnology an efficient sustainable approach enhancing under stress combating insecurity.
