Multiplex Immunoassays of Plant Viruses Based on Functionalized Upconversion Nanoparticles Coupled with Immunomagnetic Separation
Figure 8
Upconversion fluorescence spectra obtained after anti-ToRSV antibody-conjugated UCNPs/SiO2 and “MNPs-BPMV” immunocomplexes are mixed: the fluorescence spectra of the supernatant (curve 1) and the resuspended deposit (curve 2) after magnetic separation (a); upconversion fluorescence spectra obtained after anti-ToRSV antibody-conjugated UCNPs/SiO2 and “MNPs-ToRSV” immunocomplexes are mixed: the fluorescence spectra of the supernatant (curve 1) and the resuspended deposit (curve 2) after magnetic separation (b).
