Summary: A new BiVO4-carboxylated graphene (cG)-WO3 Z-scheme heterojunction was constructed for determination of oxytetracycline (OTC). The photocurrent on the BiVO4-cG-WO3/FTO photoelectrode was 4.4 times higher than that on the control BiVO4-WO3/FTO photoelectrode due to the energy level match and charge separation. By attaching an amino-functionalized OTC aptamer and hexaammonium ruthenium(III) to the BiVO4-cG-WO3/FTO photoelectrode, the photocurrent response to OTC binding was increased.

Summary: A photoelectrochemical (PEC) aptasensor based on a novel Z-scheme heterojunction of bismuth sulfide-carbon nitride (Bi2S3-C3N4) was developed for sensitive and selective detection of oxytetracycline (OTC). The photocurrent intensity of the constructed Bi2S3-C3N4 heterojunction was significantly higher than that of pure Bi2S3, due to the effective separation of photogenerated electron-hole pairs by the Z-scheme route. The increased photocurrent in the presence of OTC was attributed to the oxidation by the generated holes, as confirmed by electron spin resonance technique.

Summary: A novel approach of accelerating hole transfer from Blue-TiO2 (BTiO2) to N-hydroxyphthalimide (NHPI) was explored to improve the efficiency of visible light absorption. The introduction of NHPI acted as a hole mediator, enhancing the photocurrent value of NHPI/B-TiO2 by 2.7 times. This method was further used to construct a PEC aptasensor for the sensitive detection of diazinon (DIA) with a low detection limit of 0.03 nM.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
