Abstract: Fipronil (FPN) is one of the widely used pesticides in plant cultivation and animal husbandry, causing extensive pollution to various environmental media such as water, soil, and plants. To address the challenge of trace detection of fipronil (FPN) in complex environmental matrices, this study designed a semi-antigen through computer simulation, modified carrier proteins, and … Read more
Inspired by the interaction between metal porphyrins (such as hemoglobin) and gas molecules in nature, the Zhang Tong team at Jilin University has successfully developed a conductive polymer composite material (PANI/PEDOT:PSS) functionalized with copper tetraphenylporphyrin (CuTPP) for high selectivity NO₂ detection at room temperature. This sensor utilizes the unique π-back bonding mechanism between CuTPP and … Read more
