Summary: A photoelectrochemical molecular imprinting sensor based on Au/TiO2 nanocomposite was developed for the detection of dibutyl phthalate (DBP). Through the growth of TiO2 nanorods by hydrothermal method and electrodeposition of gold nanoparticles on TiO2, the Au/TiO2 composite was fabricated. Then, a molecular imprinted polymer (MIP) was electropolymerized on the Au/TiO2 surface to enhance the photoelectric conversion efficiency and sensitivity of the sensor. The MIP also provided highly selective recognition sites for DBP molecules. The sensor exhibited a wide linear range, low limit of detection, and good selectivity, showing promising applications in environmental analysis.

Summary: In order to monitor the residual of neonicotinoids, a novel smartphone-enabled molecularly imprinted ratiometric fluorescence sensing system was developed for on-site detection of thiamethoxam (TMX). The system utilized blue-emission carbon dots (B-CDs) wrapped with a molecularly imprinted layer (MIPs) as response signal, and red-emission carbon dots (R-CDs) as internal reference. The fluorescence signal ratio increased with TMX concentration, resulting in a color change from red to blue. The system showed a satisfactory limit of detection (LOD) of 13.5 nM (fluorescence analysis) and 70.1 nM (visual determination), and demonstrated excellent reliability for TMX detection in actual samples with recovery rates ranging from 91.40% to 105.7%. Therefore, this sensing system offers promising prospects for visual detection of pesticide residues in complex environmental samples.

Summary: This study presents a novel probe based on tungsten trioxide quantum dots (WO3-x QDs) and molecularly imprinted polymers for the detection of trace tetracycline (TC) in complex food matrices. The WO3-x QDs exhibit fluorescence enhancement on TC, while TC quenches the fluorescence of WO3-x QDs. By utilizing the blue and yellow emissions of WO3-x QDs and TC, respectively, a ratiometric fluorescence detection method was developed. The incorporation of molecular imprinting technology improved the selectivity of the probe, allowing for both selective detection of TC and visual detection from blue to yellow.

Summary: This study aimed to develop a simple, rapid, and highly sensitive photoelectrochemical (PEC) sensor for the detection of dibutyl phthalate (DBP), a major phthalate plasticizer pollutant in the environment. The sensor utilized a dual identification strategy based on a metal organic framework (MOF) and Cu2O heterostructure, incorporating aptamer recognition mechanism with molecular imprinted technology (MIT). The sensor exhibited highly specific determination of DBP due to the strong light adsorption ability and enhanced photocurrent of the Cu3(BTC)2/Cu2O hybrid under visible light irradiation, as well as the double recognition mechanism of aptamer and MIT. The designed sensor achieved a linear range from 0.1 pM to 1.0 nM and an extremely low detection limit of 0.035 pM under optimal experimental conditions, showing good reliability and practicability in real samples assay. This study extends the application of PEC sensors in the detection of plasticizer contaminants.

Summary: An effective strategy is proposed to construct a highly sensitive ratiometric fluorescence sensing platform for microcystins (MCs) based on a dummy molecularly imprinted polymer using metformin as a template. The imprinted nanohybrids of carbon dots (CDs) combined with fluorescein isothiocyanate (FITC) are synthesized (CDs-FITC-SiO2@MIP), in which the CDs and FITC serve as assisted response signals and reference enhancement signals, respectively. This method has great potential for monitoring MCs in complex systems.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
