“…Electrochemistry is widely used to characterize the electron mobility of materials or to analyze the redox reactions occurring in materials, etc. It has gained wide attention for use in sensors 17–19 and energy storage. 20 Microplasma electrochemistry (MIPEC) methods are a new type of AOPs in which the system consists of a DC power supply, an atmospheric-pressure plasma electrode and a Pt counter electrode, which is quite convenient and small and different from other plasma devices.…”

Rapid and accurate detection of nitrite in the aqueous environment is extremely important for ecological safety and human health. In this paper, the Raman detection of nitrite by a NiFe2O4@Ag sensor in water is enhanced by an extra magnetic field collaborated with surface plasma. Most importantly, it is demonstrated that the magnetic field enhances the Raman peak intensity through not only the effect of magnetic aggregation but also the magnetic field‐induced dielectric polarization effect. In this way, the NO2− can be detected in a wide linear range from 10−8 to 10−3 mol L−1, and the limit of detection (LOD) can reach as low as 1.25 × 10−9 mol L−1, which is 5.69 times lower than that in the absence of an external magnetic field. Similarly, the sensitivity under the magnetic field is 2.65 times that without the magnetic field. In addition, the sensor also shows superior detection ability to NO2− in real samples. Given the excellent capability of the magnetic field‐enhanced Raman spectra, the reported strategy offers new thoughts on how to enhance the detection ability by an external magnetic field and show the great application potential in real water bodies.

Metal‐organic frameworks (MOFs) are a new variety of solid crystalline porous functional materials. As an extension of inorganic porous materials, it has made important progress in preparation and application. MOFs are widely used in various fields such as gas adsorption storage, drug delivery, sensing, and biological imaging due to their high specific surface area, porosity, adjustable pore size, abundant active sites, and functional modification by introducing groups. In this paper, the types of MOFs are classified, and the synthesis methods and functional modification mechanisms of MOFs materials are summarized. Finally, the application prospects and challenges of metal‐organic framework materials in the biomedical field are discussed, hoping to promote their application in multidisciplinary fields.
