The presence of pesticide residues in textiles poses a risk to human health. We established a robust and high-throughput liquid chromatography-tandem mass spectrometry method for the determination of 115 pesticide residues in textiles. In this study, we evaluated high-performance liquid chromatography-tandem mass spectrometry conditions and sample extraction methods, including separation performance of different columns, mass conditions, extraction solvent, and extraction time.

The increasing reliance on electronic devices has created a pressing demand for high-performance and sustainable electromagnetic interference shielding materials. While conventional materials, such as metals and carbon-based composites, offer excellent shielding capabilities, they are hindered by high costs, environmental concerns, and limitations in scalability. Polysaccharide-based materials, including cellulose, chitosan, and alginate, represent a promising alternative due to their biodegradability, renewability, and versatility.

Comparing to the solvent-based and waterborne polyurethanes (PU), the solvent-free reactive PU (RPU) is prepared via in-situ polymerization and film-formation of isocyanate-capped prepolymers and macromolecular polyols in solvent-free system. Thus, the carbon emissions and environmental pollutions are significantly reduced. However, the rapid polymerization also challenges the well control of structure and properties, especially the ordered microstructures.

Identification of constitutive herbs in an herbal product is critical for ensuring its quality and efficacy. However, current identification methods often lack universality, entail long durations, and involve complex procedures. Therefore, there is an urgent need to develop innovative methods for identifying constitutive herbs.

Rapid and accurate detection of Chlamydia psittaci, the causative agent of psittacosis, is crucial for both human and animal health but presents significant challenges, particularly in grassroots health institutions. Our previous PDTCTR fluorescence sensing platform, which combined the engineered Cas12f1_ge4.1 system with recombinase polymerase amplification (RPA), significantly enhanced detection efficiency.
