Magnetic-Plasmonic Hybrid Nanobeads Designed for Imaging and Isolation of Cellular Organelles

Magnetic-plasmonic nanoparticles offer the combined benefits of both a magnetic probe as well as additional imaging modes usually associated with noble metal nanoparticles. Professor Shinya Maenosono (Japan Advanced Institute of Science and Technology) explores the synthesis, characterization, and proof-of-concept application of Ag/FeCo/Ag core/shell/shell magnetic-plasmonic nanobeads for imaging and isolation of cellular organelles (autophagosomes of COS-1 cells).
