Synthesis of Magnetic Nanoparticles for Biosensing

Professor Randal Lee (University of Houston, USA) discusses design considerations for iron oxide magnetic nanospheres and nanocubes used for biosensing, including synthetic procedures, size, and shape. The effects of these variables are discussed for various volumetric-based and surface-based detection schemes.
