Hefei Research Institute realizes rapid detection of multiple toxic organic pollutants

Recently, Meng Guowen's research group, researcher of the Nanomaterials and Device Technology Research Department of the Institute of Solid State Physics, Chinese Academy of Sciences, studied the construction of a three-dimensional flexible surface enhanced Raman scattering (SERS) substrate and its rapid and sensitive response to organic pollutants New progress has been made in this regard

Compared with conventional pollutants, toxic organic pollutants have the characteristics of non-degradability, bioaccumulation, migration and high toxicity, which threaten human health and the ecological environment

In view of this, the researchers used a three-dimensional network structure composed of bacterial nanocellulose as a flexible carrier, and used the silver mirror reaction to grow uniformly distributed Ag nanoparticles on its surface in situ to obtain a high-density Ag nanoparticle-modified bacterial cellulose flexibility.

The research work is supported by the National Natural Science Foundation of China, the Key Research Project of Frontier Science of the Chinese Academy of Sciences, and the Natural Science Foundation of Anhui Province
