Novel magneto-optical sensors based on anisotropic magnetic nanomaterials for detecting biological agents
2020
Biosensors are developed that use nanoparticles with direction-dependent magnetic properties detected optically in real time by a low-coherent interferometry. Antibody-functionalized one- and two-dimensional nanoparticles (nanorods and nanodiscs) were used as anisotropic materials. The biosensors form the signal due to synchronized detection of a shift of the interference spectrum during a periodic actuation of anisotropic particles by an external magnetic field.
