Sulfur dioxide is a critical factor in evaluating food safety, as excessive intake can lead to various adverse reactions. Additionally, viscosity is a key indicator of food quality. However, to date, dual-response probes capable of detecting both viscosity and sulfur dioxide in food remain scarce. In this study, we present a novel fluorescent probe, BZID-OH, designed for the simultaneous detection of sulfur dioxide and viscosity in food. Moreover, BZID-OH is also effective for sulfur dioxide detection in living cells. These findings suggest that BZID-OH has the potential to serve as an effective dual-response fluorescent probe for monitoring both sulfur dioxide levels and viscosity in food, offering a valuable tool for food safety and quality assessment.

Microplastics have increasingly accumulated in sulfate- and organic matter-rich mangrove ecosystems, yet their effects on microbially mediated carbon and sulfur cycling in sediments remains poorly understood. In this study, we performed a 70-day anaerobic microcosm experiment to examine the effects of polylactic acid (PLA) microplastics with different sizes on sulfate reduction and dissolved organic carbon (DOC) degradation in mangrove sediments. Our results demonstrated that millimeter-scale PLA (mm-PLA) more effectively enhanced sulfate reduction, sulfur isotope fractionation, reduced sulfide production, and carbon dioxide (CO) emission compared to micrometer-scale PLA (m-PLA).

Overcoming tumor antioxidant defenses remains a critical challenge for reactive-oxygen-species-mediated tumor therapies. To address this problem, herein, a theranostic nanomedicine designated as CCM@MIB has been elaborately constructed. Homologous cancer cell membrane (CCM) camouflage significantly enhances the selective accumulation of the nanomedicine at tumor sites.

Sulfur dioxide (SO) is one of the hazardous gases during coal or hydrogen sulfide combustion in petrochemical and coal-related industries. Unfortunately, SO is released into the atmosphere in most SO-involved industries. The high concentration of SO in the atmosphere leads to acid rain, which leads to various damage and destruction of the environment.
