“…Based on the above analysis, it can be suggested that the enhanced POD-like performance of the CuO/NiO NTs may have resulted from the following reasons. First, the tubular CuO/NiO NTs show an apparent hollow pore inside the material, which can serve as the main diffusion channel for molecules and endow a desirable mass transfer of reactants to achieve a promoted catalytic property, which is in accordance with previous reports. ,,− Second, the good affinity between the CuO/NiO NTs and TMB substrate benefits us to promote the catalytic activity, which is confirmed by the above kinetic result of a low K m value toward TMB (Figure ). Third, the heterogeneous structure composed of NiO and CuO facilitates the electron transfer from the catalyst to the H 2 O 2 , promoting the POD-like activity, which is proven by the above electrochemical analysis (Figure S4b).…”

Isoniazid is an antibiotic primarily used in clinical treatment of tuberculosis, but excessive usage can lead to serious consequences such as hepatotoxicity, neurotoxicity, and even coma and death. Therefore, it is critical to exploit a quick, facile, and acute way for isoniazid analysis. In this work, we have demonstrated an efficient electrospinning–carbonation–wet chemistry reaction–calcination process to fabricate CuO/NiO nanotubes (NTs) as a promising nanozyme for peroxidase (POD) mimicking. In virtue of the distinct tubular structure and synergy between CuO and NiO from the mechanisms of both electron transfer and hydroxyl radical generation, a remarkably improved catalytic activity is realized for the CuO/NiO NTs compared with bare CuO and NiO samples. According to the admirable POD-like property, a rapid colorimetric detection for isoniazid is accomplished with a detection limit of 0.4 μM (S/N = 3) and favorable selectivity. In addition, the sensing capability of isoniazid in a real sample is also investigated with satisfactory results. This work offers a novel tactic to fabricate high-performance nanozymes with efficient isoniazid sensing capabilities to address challenges in disease treatment efficacy and public safety monitoring.

“…To analyze the conformation and chemical valence of chemical bonds in N-Mn 3 O 4 NPs, high-resolution XPS analysis of various elements was conducted. The high-resolution XPS spectra of N 1s had three peaks at 398.9, 399.5, and 400.9 eV (Figure A), which were assigned to pyrrolic- N , O–Mn–N, and −NH 2 , respectively. − Pyrrolic- N and −NH 2 suggested that unbroken His may still be present in N-Mn 3 O 4 NPs. The presence of characteristic peaks of His skeleton in N-Mn 3 O 4 NPs was further demonstrated using Fourier-transform infrared spectroscopy (FT-IR) (Figure S4).…”

Defect-engineered nanomaterials have been found to improve catalytic activity, making them highly desirable for biosensor preparation. Nitrogen doping is an effective method for introducing defects in nanomaterials, and amino acids containing nitrogen atoms can be used as a nitrogen source for doping nanozymes. In this study, nitrogen-doped N-Mn 3 O 4 nanoparticles (NPs) were synthesized using various amino acids as nitrogen sources. The results indicate that N-Mn 3 O 4 NPs doped with histidine as a nitrogen source exhibit the highest oxidase-like activity. Additionally, N-Mn 3 O 4 NPs have a V max that is 5.4-fold higher and a K m that is 1/2-fold lower than Mn 3 O 4 , suggesting that histidine-doped N-Mn 3 O 4 NPs can be used to create highly active oxidase-like enzymes. A dual-modal sensor utilizing both ratiometric fluorescence and smartphone-based colorimetry method with a smartphone has been developed for the detection of acid phosphatase, based on N-Mn 3 O 4 NPs with high enzymatic activity. This study presents an approach to constructing highly active oxidase-like and realizing a highly sensitive assay for detecting acid phosphatase with high interference resistance. The mechanisms underlying the improved performance of nitrogen-doped nanomaterials and their potential applications in biosensor fields were also discussed.

“…In past two decades, metal organic frameworks (MOFs) and covalent organic frameworks (COFs) have attracted tremendous attentions due to their tunable structures, high porosity, [ 1 ] programable properties, [ 2 ] and high stability.

Comprehensive SummaryCovalent/metal organic frameworks are highly attractive due to their tunable structure and properties, and broad applications in multiple fields. However, they still suffer from numbers of drawbacks including low solubility, harsh synthesis and fabrication, and low mechanical flexibility. Herein, we report a new organic framework consisting of macrocycles and organic frames in its periodic structure, and denote it as macrocycle organic polymer (MOP). The size‐tunable macrocycles containing peripheral furan units are synthesized by anionic ring‐opening polymerization, which undergo a reversible Diels‐Alde reaction with bismaleimide to generate/degrade MOPs at given temperatures. Relying on above features, MOPs exhibit excellent flexibility, healable ability and recycle ability. Interestingly, owing to the “living” nature of anionic ring‐opening polymerization, MOPs can self‐grow into bigger sizes in the presence of monomer and catalysis, analogs to the living creatures. Moreover, their high porosity and rich thioether structure enable them as good metal ion absorbers and promising applications in wearable electronics.
