TL;DR: Mesoporous material supported CoFe2O4 magnetic nanoparticles possess unique peroxid enzyme/oxidase-like activity, and react with luminol to yield a novel chemiluminescence without the need of H2O2, and could be reversibly controlled by their pH.
Abstract: Mesoporous material supported CoFe2O4 magnetic nanoparticles possess unique peroxidase/oxidase-like activity, and react with luminol to yield a novel chemiluminescence without the need of H2O2. Their oxidase-like activity shows pH and support dependence, and could be reversibly controlled by their pH. This offers a new method for manipulating the enzyme-like activity of nanoparticles.

TL;DR: In this article , a series of nickel phosphate (NiP) counterparts with well-defined structures and definable compositions, and further their bifunctional sensing performance for H2O2 and N2H4 were investigated, where the ratio of 4:3 prepared NiP, with pure ingredient, amorphous states and 2D scaly nanosheets uniformly decorated 3D hollow scaffolds, collectively reveals rich electrocatalytic sites, shorten ion transfer/diffusion channels and excellent electrical conductivity, thus affording an significant enhancement for its electrochemical behaviors.
Abstract: Rationally designing of transition metal phosphate (TMP) with charming structure and exploiting their electroanalytic functionalities are of great potential and challenging. Herein, in-situ adoption of MOF as the framework and skillfully regulation of the evolution process through the mass ratios of sodium phosphate (namely as both etchants and reactants) and Ni-MOFs led to the configuration of a series of nickel phosphate (NiP) counterparts with well-defined structures and definable compositions, and further their bifunctional sensing performance for H2O2 and N2H4 were investigated, where the ratio of 4:3 prepared NiP, with pure ingredient, amorphous states and 2D scaly nanosheets uniformly decorated 3D hollow scaffolds, collectively reveals rich electrocatalytic sites, shorten ion transfer/diffusion channels and excellent electrical conductivity, thus affording an significant enhancement for its electrochemical behaviors, especially its low detection limit (27.9 nM and 45.1 nM) and wide measurable range (0.001–2.6 mM and 0.005–4.5 mM) for H2O2 and N2H4, respectively. Additionally, its powerful anti-interference and recognition for H2O2 and N2H4 in water samples verify the practicality of our electrochemical platforms. Our design establishes the promising strategy for engineering of new class MOF-derived diversified functionally materials for electroanalytical application and beyond.

TL;DR: This review discusses various nanomaterials that have been explored to mimic different kinds of enzymes and covers their kinetics, mechanisms and applications in numerous fields, from biosensing and immunoassays, to stem cell growth and pollutant removal.
Abstract: Over the past few decades, researchers have established artificial enzymes as highly stable and low-cost alternatives to natural enzymes in a wide range of applications. A variety of materials including cyclodextrins, metal complexes, porphyrins, polymers, dendrimers and biomolecules have been extensively explored to mimic the structures and functions of naturally occurring enzymes. Recently, some nanomaterials have been found to exhibit unexpected enzyme-like activities, and great advances have been made in this area due to the tremendous progress in nano-research and the unique characteristics of nanomaterials. To highlight the progress in the field of nanomaterial-based artificial enzymes (nanozymes), this review discusses various nanomaterials that have been explored to mimic different kinds of enzymes. We cover their kinetics, mechanisms and applications in numerous fields, from biosensing and immunoassays, to stem cell growth and pollutant removal. We also summarize several approaches to tune the activities of nanozymes. Finally, we make comparisons between nanozymes and other catalytic materials (other artificial enzymes, natural enzymes, organic catalysts and nanomaterial-based catalysts) and address the current challenges and future directions (302 references).

Abstract: Carbon nanodots (C-dots) have generated enormous excitement because of their superiority in water solubility, chemical inertness, low toxicity, ease of functionalization and resistance to photobleaching. In this review, by introducing the synthesis and photo- and electron-properties of C-dots, we hope to provide further insight into their controversial emission origin (particularly the upconverted photoluminescence) and to stimulate further research into their potential applications, especially in photocatalysis, energy conversion, optoelectronics, and sensing.

TL;DR: This review systematically introduces the classification, catalytic mechanism, activity regulation as well as recent research progress of nanozymes in the field of biosensing, environmental protection, and disease treatments, etc. in the past years.
Abstract: Because of the high catalytic activities and substrate specificity, natural enzymes have been widely used in industrial, medical, and biological fields, etc. Although promising, they often suffer from intrinsic shortcomings such as high cost, low operational stability, and difficulties of recycling. To overcome these shortcomings, researchers have been devoted to the exploration of artificial enzyme mimics for a long time. Since the discovery of ferromagnetic nanoparticles with intrinsic horseradish peroxidase-like activity in 2007, a large amount of studies on nanozymes have been constantly emerging in the next decade. Nanozymes are one kind of nanomaterials with enzymatic catalytic properties. Compared with natural enzymes, nanozymes have the advantages such as low cost, high stability and durability, which have been widely used in industrial, medical, and biological fields. A thorough understanding of the possible catalytic mechanisms will contribute to the development of novel and high-efficient nanozymes, and the rational regulations of the activities of nanozymes are of great significance. In this review, we systematically introduce the classification, catalytic mechanism, activity regulation as well as recent research progress of nanozymes in the field of biosensing, environmental protection, and disease treatments, etc. in the past years. We also propose the current challenges of nanozymes as well as their future research focus. We anticipate this review may be of significance for the field to understand the properties of nanozymes and the development of novel nanomaterials with enzyme mimicking activities.
