In this study, a novel double-emission lanthanide MOF fluorescence probe (Eu-Zn-MOF) was designed for monitoring MG in water by post-synthetic modification (PSM) to Zn-MOF synthesized by a simple hydrothermal method. Eu-Zn-MOF exhibits excellent photoluminescence properties, making it suitable as a ratiometric fluorescence sensor (<i>I</i>₄₁₀/<i>I</i>₆₁₅) for the sensitive detection of MG. MG effectively quenches the luminescence of Eu³⁺ at 615 nm, while the luminescence of the Zn-MOF frame at 410 nm remains unaltered. The fluorescence sensing platform had a relatively wide linear range (0–30 µM), low detection limit (9.8 nM), high sensitivity, and rapid response time (within 1 min). At the same time, the recovery of actual samples was 90.2–107.0%, and the relative standard deviation (RSD) was ≤ 3.82%. Simultaneously, by combining the smartphone color recognition APP with RGB analysis, a portable smartphone auxiliary sensing platform was established to realize the visual detection of MG.

This study presents the development of a novel, highly sensitive electrochemical sensor based on a Ti₃C₂@CoAl₂O₂ nanocomposite–modified glassy carbon electrode (GCE) for the detection of CAR in pharmaceutical and biological samples. The innovative Ti₃C₂@CoAl₂O₂ composite, synthesized and characterized through Fourier-transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy coupled with energy-dispersive spectroscopy, and thermogravimetric analysis, revealed exceptional structural integrity, morphology, composition, and thermal stability. The electrochemical properties of the modified electrode were evaluated using cyclic voltammetry and electrochemical impedance spectroscopy, demonstrating enhanced conductivity, an increased electroactive surface area, and reduced charge transfer resistance compared to the bare GCE. Differential pulse voltammetry was employed for CAR detection under optimized conditions, yielding a linear range of 0.2–5.6 μM with a regression equation <i>I</i>_pa (μA) = 0.133 <i>C</i>_CAR (μM) + 0.09 (<i>R</i>² = 0.993).

The immunoplatform is constructed using screen-printed electrodes where capture antibody is immobilized through the chemistry of diazonium salts. CeO₂NPs exhibit robust pseudo-peroxidase activity even at high substrate concentrations. They are covalently functionalized in a simple manner after carboxylation with a detector antibody (dAb), acting dually as a nanozyme and nanocarrier for sensing bioreceptors.

However, NIC can pose potential risks, such as DNA damage and adverse vasodilation effects in vivo. This study introduces an innovative fluorescent nanosensor for the detection of NIC in food samples. The sensor utilises sulphur and nitrogen co-doped carbon dots (S,N-CDs) derived from eco-friendly materials, Turbo bruneus and L-cysteine, encapsulated within a molecularly imprinted polymer (S,N-CDs@MIP). The sensor operates on a “Turn Off” mechanism, where NIC binding results in decreased fluorescence intensity, effectively detecting NIC in the 1–10 µM concentration range. Excellent sensitivity is indicated by the calibration curve, which displays a strong linear connection between NIC concentration and fluorescence intensity (<i>Y</i> = 0.0612x + 0.0689, <i>R</i>² = 0.9996) and a detection limit of 48.1 nM. The sensor is selective, user-friendly, and cost-effective, with NIC recoveries in food samples ranging from 96.33 to 103.23% and low RSD values (0.81 to 4.89%). Moreover, we utilized the AGREEMIP software to assess the greenness of MIP synthesis processes. This tool evaluates 12 criteria encompassing energy requirements, synthesis specifics, and the environmental impact of reaction components, providing a comprehensive measure of the produced MIP's sustainability.
