Jilin University Zhang Tong Team | Bio-inspired Room Temperature NO₂ Sensor: π-Back Bonding Mechanism Achieves High Selectivity Detection

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

Nitrogen dioxide (NO2) in the air not only causes severe environmental pollution but also poses a significant threat to human health, making it an “invisible killer” that endangers both human health and the environment. Currently, there are many challenges in NO2 sensor technology that severely limit its application: difficulties in operating at room temperature, high … Read more
