Afacile fabrication of spherical and beanpod-like magnetic-fluorescent particles with targeting functionalities

Magnetic-fluorescent particles with targeting functionalities were fabricated by a modified Stöber method and two shapes (spherical and beanpod-like) were obtained by simply tuning the reaction temperature. The two multifunctional probes combined the useful functions of magnetism, fluorescence and F... Full description

description: Magnetic-fluorescent particles with targeting functionalities were fabricated by a modified Stöber method and two shapes (spherical and beanpod-like) were obtained by simply tuning the reaction temperature. The two multifunctional probes combined the useful functions of magnetism, fluorescence and FA (folic acid)-targeting recognition into one entity. The products were characterized by scanning electron microscopy, transmission electron microscopy, photoluminescence spectroscopy, confocal laser scanning microscopy, by a superconducting quantum interference device and by Fourier transform infrared spectroscopy. The experimental results show that the products possessed rapid magnetic response, relatively strong fluorescent signal, higher photostability and FA-targeting recognition as well as good water-dispersibility, suggesting that they would have potential medical applications in biolabeling and bioimaging.
