“…The magnetic relaxation transfer switch (MRS) sensor based on magnetic nanoparticles has the characteristics of simple operation and fast response, and the magnetic nanoparticles enable MRS sensors to effectively separate impurities from complex samples and accurately detect targets. Some scholars 119 have combined it with FL to construct a dual-mode sensor. First, fluorescent magnetic nanoparticles (MNP 300 @SiO 2 ) were prepared by coating silica on the surface of MNP 300 and fusing fluorescein isothiocyanate (FITC) within the silica layer 2 (FITC),coupled with an aptamer (Apt) to form a capture probe.…”
