In this study, magnetic fluorescent polymer microspheres were prepared by incorporating Fe304 nanoparticles and CdSe/ZnS quantum dots（QDs） into hyper-crosslinked microporous polymer micro- spheres（HCMPs） via the in situ coprecipitation method and swelling-diffusion. The HCMPs predominantly have mi- cropores, and their specific surface area is as high as 703.4 m2/g. The magnetic-fluorescent microspheres maintain the superparamagnetic behavior of Fe304, and the saturation magnetization reaches 38.6 A.m2/kg. Moreover, the composite microspheres exhibit an intense emission peak at 530 nm and achieve good fluorescence.展开更多
