The proliferation of micro/nanoplastics (MNPs) has emerged as a pivotal environmental issue, largely due to their potential for human exposure. Consequently, the development of sensitive and efficient detection methodologies is paramount for elucidating their environmental footprint. Here, we report a novel three-dimensional (3D) surface-enhanced Raman scattering (SERS) sensor, which integrate TiCT/TiO/WO semiconductor heterostructure, for the rapid and sensitive detection of MNPs in environmental matrices.

Food allergy is increasingly prevalent and poses notable health risks, which underscores the urgent need to develop reliable and sensitive detection methods for effective identification of food allergens. This study aims to address the limitations of existing methods by developing an immunoassay utilizing bacteriophage/carbon dots (CDs)@silica core-shell nanospheres. Two CDs with different emission wavelengths (513 nm for Green CDs, 645 nm for Red CDs) were synthesized for signal development and amplification.

As consumers increasingly prioritize food safety and nutritional value, the dairy industry faces a pressing need for rapid and accurate methods to detect essential nutritional components in milk, such as fat, protein, and lactose. Hyperspectral imaging (HSI) technology, known for its non-destructive, fast, and precise nature, shows great promise in food quality assessment. However, the high dimensionality of HSI data poses challenges for effective band selection and model optimization.
