Summary: There is a need to develop novel nanosensors for the sensitive and facile detection of glyphosate pesticides in water. This study presents a dual emissive carbon dot system that can optically detect glyphosate at different pH levels. The system utilizes blue and red fluorescence emissions and employs a ratiometric self-referencing assay. The red fluorescence is quenched by glyphosate, while the unaffected blue fluorescence serves as a reference. These carbon dots can be used as cost-effective and simple environmental nanosensors for the detection of other pesticides and contaminants in water.

Summary: In this study, a water-soluble and highly fluorescent nanosensor based on N-doped carbon quantum dots (CDs) was successfully fabricated for selective sensing of hypochlorite. The nanosensor showed high stability under various interferences and exhibited significant selectivity towards ClO-. It could detect ClO- concentration in the range of 0.1-50 μmol.L-1 with a sensitivity of 0.03 μmol.L-1. Additionally, the nanosensor could be applied for determination of ClO- in environmental water and visualizing ClO- in living cells.

Summary: A newly designed microcrystalline Cd(ii)-MOF fluorescent sensor, 1-NH2, was synthesized for off-state detection utilizing the photo-induced electron transfer process, showing high selectivity and sensitivity, especially towards glyphosate and Cr3+ with low detection limits. The fluororescent enhancement mechanism is associated with the inhibition of the PET process stimulated by the dissociation of the framework in the presence of glyphosate and Cr3+.

Summary: An effective fluorescent probe for analysis of p-aminoazobenzene (p-AZO) was established using carbon dots (CDs) and magnetic molecularly imprinted nanomaterial. The sensitivity of the constructed probe was greatly improved through the introduction of magnetic solid phase extraction. Factors affecting the enrichment efficiency and detection performance of p-AZO were optimized. The probe exhibited good selectivity, sensitivity, and linearity for p-AZO determination, with a low detection limit and satisfactory recoveries in real water samples.
