To realize highly sensitive and reproducible SERS performance, a new route was put forward to construct uniform film by using magnetic composite microspheres. In the experiment, monodisperse Fe3O4@SiO2@Ag microspheres with hierarchical surface were developed used as building block of substrate, which not only realized fast capturing analyte through dispersion collection under external magnet but also could be built into magnetically induced self-assembly. By R6G probe molecule, as-obtained...
Aflatoxin B1 (AFB1), one of the most toxic mycotoxins, has undergone a wide range studies over years.
