FC-40 is a colorless and tasteless fluorine oil, which has important application value in the fields of medical equipment and biological detection. In this study, the terahertz technology was combined with microfluidic technology to study the terahertz transmission characteristics of FC-40 after standing under electric and magnetic fields for different time, respectively. It is found that the transmission intensity of terahertz spectra of FC-40 increases with the increase of standing time in external electric field and magnetic field. The microscopic change is deduced from the change of transmission intensity of liquid, and the influence of electric field and magnetic field on polar covalent bond of C-F is analyzed in detail. The results show that the transmission intensity of FC-40 increases with the increase of standing time in electric and magnetic fields. This study provides technical support for improving the detection sensitivity of biomolecule in fluorine oil.
