Inorganic phosphori are widely used in food, whose quantitative detection method is of significance. This work presents a Sm-DDB (HDDB = 1,3-di(3',5'-dicarboxylphenyl)benzene), which acts as a ratiometric fluorescence sensor to monitor PO, HPO, and (PO) with high sensitivity. The determination factors of pH, MOF dosage, and fluorescence response time are optimized as 7.

Real-World Particle Emissions from a Modern Heavy-Duty Diesel Vehicle during Normal Operation and DPF Regeneration Events: Impacts on Disadvantaged Communities.

Environ Sci Technol

January 2025

Center for Environmental Research and Technology (CE-CERT), Bourns College of Engineering, University of California, 1084 Columbia Avenue, Riverside, California 92507, United States.

We assessed the real-world particulate emissions of a goods movement diesel vehicle, with an emphasis on total particle number and solid particle number emissions at different cutoff sizes. The vehicle was tested on routes in the South Coast Air Basin (SCAB) of California, representative of typical goods movement operation between the ports to warehouses and logistic centers with a mixture of urban and highway driving, as well as elevation change. We evaluated emissions during normal vehicle operation and diesel particulate filter (DPF) active regeneration events.

Multimodal nanoenzyme-linked aptamer assay for Salmonella typhimurium based on catalysis and photothermal effect of PB@Au.

Mikrochim Acta

January 2025

Shandong Provincial Key Laboratory of Animal Resistance Biology, Key Laboratory of Food Nutrition and Safety of Shandong, College of Life Science, Normal University, Shandong Normal University, Jinan, 250014, People's Republic of China.

A composite nanomaterial of Prussian blue@gold nanoparticles (PB@Au) with catalytic and photothermal properties was proposed, which combined with anti-matrix interference aptamers to achieve robust specificity and sensitivity in the detection of Salmonella typhimurium (S. typhimurium). The detection probe, PB@Au-Aptamer (PB@Au-Apt), was designed to exhibit high specificity for the target and catalyze the signal generation to produce a color change, thereby enabling rapid detection.
