摘要
Highly anisotropic rods containing an- ionic magnetic nanoparticles and organic fluorescent nanospheres (see image) are synthesized using an electrostatic co-assembly strategy in the presence of cationic polyelectrolytes. The hybrid elongated architectures maintain the superparamagnetic properties of the γ-Fe2O3 constituents, as evidenced by their in-phase response to an external rotating magnetic field. © 2009 Wiley-VCH Verlag GmbH & Co.
