Chemiluminescence (CL) is regarded as a better method for the detection of reactive oxygen species (ROS). However, weak CL intensity prevents its further application. Many nanomaterials have been developed to enhance intensity, and mixed-ligand MOFs incorporating additional metals or organic ligands exhibit high efficiency in catalyzing. In this work, one kind bimetallic metal–organic framework (Ni-Co m-MOF) was synthesized using solvothermal methods. The material morphologically characterized demonstrated be dense spherical flower-like structure. addition Ni-Co m-MOFs significantly enhanced luminol-H2O2 system by nearly 2,000-fold. enhancement found through research hydrogen peroxide catalyzed create hydroxyl radicals, etc., which reacted more easily with luminol. Herein, significant identified, provides ideas improving sensitivity signal-to-noise ratio development detectors.

Ratiometric lanthanide coordination polymers (Ln-CPs) are advanced materials that combine the unique optical properties of ions (e.g., Eu3+, Tb3+, Ce3+) with structural flexibility and tunability polymers. These widely used in biological chemical sensing, environmental monitoring, medical diagnostics due to their narrow-band emission, long fluorescence lifetimes, excellent resistance photobleaching. This review focuses on composition, sensing mechanisms, applications ratiometric Ln-CPs. The mechanism relies two distinct emission bands, which provides a self-calibrating, reliable, precise method for detection. relative intensity ratio between these bands varies concentration target analyte, enabling real-time monitoring minimizing interference. approach is particularly suitable detecting trace analytes use complex environments where factors like background noise, temperature fluctuations, light variations may affect results. Finally, we outline future research directions improving design synthesis Ln-CPs, such as incorporating long-lifetime reference luminescent molecules, exploring near-infrared systems, developing up-conversion or two-photon materials. Progress areas could significantly broaden scope Ln-CP applications, especially biosensing, other fields.

Thiram (THI) and asomate (ASO) are frequently detected agrochemicals in food samples due to widespread use as fungicides. However, their detection suffers from matrix interference, or the necessity of derivatization before measurement. Integrating HPLC with a post-column carbon dots (CDs)-enhanced chemiluminescence (CL) system makes it possible simultaneously separate selectively detect ASO THI fruit free deep purification. The studies on mechanisms demonstrated that CD intermediates anionic radical were responsible for remarkable CL enhancement THI. intensity is directly proportional fungicide concentration, ranges linearity being 5-250 μg·L
