Summary: A photocatalyst has been developed by anchoring a Ru complex on CdS quantum dots, achieving selective oxidation of HMF to DFF or HMFCA with high conversion (>81%) and selectivity (>90%). This selective conversion can work well using natural sunlight outside the laboratory, and notably achieves selective production of HMFCA through photocatalytic HMF oxidation for the first time. This photocatalyst is also applicable for the selective oxidation of other compounds with hydroxyl and aldehyde groups.

Summary: This manuscript proposes a novel strategy for designing and preparing magnetic molecularly imprinted polymers (MMIPs), and establishes a fluorescent sensor for low-cost and fast detection of Sudan I using the synthesized MMIPs. The fluorescence intensity of the MMIPs decreases linearly with the concentration of Sudan I, and the detection limit is 0.38 μM. The sensor demonstrates satisfactory performance for the quantification of Sudan I in chili powder, with a wide concentration range and good precision. The prepared MMIPs show great potential for low-cost and fast detection in food safety analysis.

Summary: A fluorescent sensor of nitrogen-doped carbon quantum dots (N-CQDs) and silica gel hybrid was developed for the quantitative detection of nitenpyram. The sensor exhibited remarkable selectivity and sensitivity towards nitenpyram. The selective sensing is attributed to the excitation light absorption of nitenpyram, leading to fluorescence quenching of the sensor.

Summary: This study reports a facile strategy to enhance the red emission of carbon dots (CDs) in aqueous solution through surface modification with polyetherimide (PEI). The PEI functionalization not only protects the red emission against quenching by water molecules, but also promotes cellular uptake of CDs and exhibits better photostability compared to commercial red emissive dye. The potential applications of this strategy in cell imaging and cell fluorescent staining have been demonstrated.
