Characterization And Manipulation Of Nanorods Via An Applied Magnetic Field, Summer Wu '13 Apr 2012

Characterization And Manipulation Of Nanorods Via An Applied Magnetic Field, Summer Wu '13

Student Publications & Research

A remote system capable of controlling the motion of magnetic nanorods was created. Two different systems, electromagnets and magnetic stirrers, were used to create continuously changing magnetic fields thus applying a constant torque to make nanorods rotate as “nano stirbars”. The system was tested on three different types of synthesized nanorods: multi-segmented Ni/Au, pure Ni, and pure Au nanorods. Ni and Au were chosen due to the combination of the magnetic properties of Ni and the biocompatible properties of Au. Variables such as length, shape, and geometries of the nanorods were characterized by a scanning electron microscope and an ...
