UV-Vis spectra of MNP-SiO2(RITC) and MUC1-MNP-SiO2(RITC).
Notes: Both MNP-SiO2(RITC) (black line) and MUC1-MNP-SiO2(RITC) (red line) show the same fluorescence peak of RITC (580 nm) (black arrow) but only MUC1-MNP-SiO2(RITC) shows a protein peak (280 nm) (red arrow).
Abbreviations: UV-Vis, ultraviolet-visible spectra; MNP-SiO2(RITC), magnetic nanoparticle-SiO2(rhodamine B isothiocyanate); MUC1, mucin 1 cell surface-associated antibody.
