Synthesis and characterization of a flexible fluorescent magnetic Fe3O4@SiO2/CdTe-NH2 nanoprobe

The quenching reaction between folic acid (FA) and Fe3O4@SiO2/CdTe with short active groups is acute and could not to accurately detect. The quenching reaction between FA and Fe3O4@SiO2/CdTe-NH2 with suitable active groups synthesized by us is mild and could be using to accurately detect.177
