The synthesis and bio-applications of magnetic and fluorescent bifunctional composite nanoparticles

摘要

Magnetic–fluorescent composite nanoparticles as a new kind of nanoparticle have attracted muchnattention in recent years. The composite nanoparticles combine the fluorescent properties, magneticnproperties and the physical properties of nano-size, so they can offer a range of potential applications,nsuch as bioseparation and bio-imaging, tumor cell localization, and even cancer treatment. ThisnMinireview will introduce the main synthesis strategies for the fabrication of magnetic–fluorescentncomposite nanoparticles, the current and potential bio-application of magnetic–fluorescentnnanocomposites, including protein and DNA separation and detection, bio-imaging and sorting in vitronand in vivo, drug delivery and the cancer treatment.
