Abstract
A method for preparing a ratiometric fluorescent sensor for phycoerythrin based on a magnetic molecularly imprinted core-shell polymer is provided. With FeOmagnetic nanoparticles as the core, blue fluorescence-emitting carbon quantum dots (B-CDs) are coupled on the surfaces of FeOmagnetic nanoparticles, and SiOshells carrying template molecules (phycoerythrin) are grown on the surfaces of FeO/B-CDs. Then, the molecularly imprinted polymer SiO-MIPs are obtained by eluting the template molecules, that is, FeO/B-CDs/SiO-MIPs are obtained. Fluorescence emission spectra of the dispersion of FeO/B-CDs/SiO-MIPs in the presence of different concentrations of phycoerythrin are measured. By fitting the linear relationship between the ratios I/Iof fluorescence emission peak intensities of phycoerythrin and B-CDs and the molar concentrations of phycoerythrin, the ratiometric fluorescent sensor for phycoerythrin is constructed.
