Magnetic and Fluorescent Silica Nanospheres
M. Bawendi and R.M. Westervelt

These fluorescent/magnetic nanocrystals composite demonstrate the ability to create multifunctional nanospheres with potential applications in the magnetically driven assembly of nanostructures.

Fluorescent (CdSe/CdZnS) and magnetic (Fe2O3) nanocrystals have been incorporated into silica core/shell nanospheres, imaged using fluorescence microscopy, and manipulated using magnetic field gradients generated by passing current through specified wires within an array. These fluorescent/magnetic composite demonstrate the ability to create multifunctional nanospheres with potential applications in the magnetically driven assembly of nanostructures.
