Summary: A portable, sensitive, and stable sensing platform based on a smartphone was developed to detect miRNA. The platform utilized a photoinduced electron transfer process to quench fluorescence, enabling sensitive detection of miRNA with a detection limit of 0.32 pM, even distinguishable by the naked eye. Furthermore, the platform demonstrated high selectivity and accurate analysis of miRNA expression levels in cancer cell samples.

Summary: In this study, a luminescent porous organic network (PON) connected by imine linkages was successfully synthesized. The PON showed strong fluorescence in water and demonstrated high selectivity and sensitivity for the detection of Cr(vi) species (CrO42- and Cr2O72-) in a turn-off manner. The possible luminescence sensing mechanism and the adsorption capacity of Cr(vi) were also discussed in detail.

Summary: A sensitive fluorescence probe based on porous Lanthanum-1,4-benzenedicarboxylic frameworks (La-BDC) was developed for selective detection of 2-chloroethyl ethyl sulfide (2-CEES) at part per billion levels. The La-BDC particles were synthesized using the solvothermal method and characterized using FTIR spectroscopy, X-ray powder diffraction, scanning electron microscopy, UV-Vis spectrometry, and fluorescence spectroscopy. The LaBDC sensor showed a sensitive detection limit (LOD = 0.0521 nM, 0.0065 ppb) and a wide linear range of 25-400 ppb for 2-CEES, along with selectivity towards 2-CEES in the presence of dimethyl methyl phosphonate and hexane.

Summary: Seawater pollution caused by heavy metal ions is a growing concern. Lead-free perovskite quantum dots (PeQDs) show great potential for metal ion detection, but traditional lead-based PeQDs have drawbacks. In this study, lead-free halide PeQDs Cs3Bi2Br9 were synthesized and used as fluorescent probes for detecting copper ions in seawater. The results showed a strong linear correlation between the degree of quenching and the contents of Cu2+, and Cs3Bi2Br9 PeQDs exhibited good sensitivity, detection limit, photostability, water stability, and selectivity. These findings suggest their potential in detecting marine heavy metal contaminants.

Summary: A novel and sensitive fluorescent probe for the detection of glyphosate pesticides has been developed based on Cu2+-modulated polydihydroxyphenylalanine nanoparticles (PDOAs). The fluorescence of PDOAs can be effectively quenched by Cu2+ and recovered in the presence of glyphosate. The proposed method exhibits high selectivity, turn-on fluorescence response, and ultralow detection limit, and has been successfully applied for the determination of glyphosate in environmental water samples.
