Ce-MOF Nanosphere as Colorimetric Sensor with High Oxidase Mimicking Activity for Sensitive Detection of H2O2

Green synthesis and characterization of Ag nanoparticles in a phytic acid/ascorbic acid/sodium hydroxide system and their application in the electrochemical detection of H2O2

“…As a by-product of industrial production such as antiseptic disinfection, paper bleaching and biochemistry, H 2 O 2 is often discharged into water without being completely treated, causing pollution to water resources. 1,2 However, excessive use or ingestion of H 2 O 2 will cause serious harm to environmental safety and human health. In addition, modern medicine has also revealed that H 2 O 2 overproduction can cause biological damage, leading to oxidative stress, arteriosclerosis and other diseases.…”

Amorphization‐Modulated Metal Sulfides with Boosted Active Sites and Kinetics for Efficient Enzymatic Colorimetric Biodetection

“…As shown in Figure 5e and Table S5 (Supporting Information), compared with some reported biocatalysts, a‐RuS 2 exhibits comparatively lower LOD value and wider linear detection range, indicating its advantages in the detection of H 2 O 2 . which can lay the foundation for its application in the cascade detection of a variety of biomolecules..

[68,69] l-cysteine is a critical amino acid that is essential for the human body and is associated with antiaging and melanin reduction. [70] The thiol group, which plays a crucial role in the production of disulfide bonds during the intramolecular crosslinking of proteins, determines how l-cysteine functions.…”

Research progress of metal–organic framework nanozymes in bacterial sensing, detection, and treatment

“…The catalytic capacity of MOF-based nanozymes mainly comes from the following two aspects: on the one hand, the redox reaction of metal ions such as Fe, Cu, Co, Ni and Ce has the catalytic activity; on the other hand, it is the natural enzyme catalytic reaction process simulated by special organic ligands (organic ligands as the electronic medium to transfer the electrons accepted by one substrate to another substrate). Depending on the enzyme activities, researchers have developed MOF-based nanozymes with different enzyme activities, mainly including peroxidase (POD), 45,46 glucose oxidase (GOx), 16,47 oxidase, 48–50 superoxide dismutase (SOD), 51–53 and catalase (CAT). 54,55 We summarize the basic features of MOF-based nanozymes in Table 1.…”
