On shape controlled nanocrystals and hybrid materials: how nanotransistors and remote controlled fluorescent probes could be realized

We present here methods to synthesise CdX nanocrystals (X=Se, Te, S) with a controlled shape. They can be spherical, elongated or branched. We also synthesise spherical magnetic nanoparticles (CoPt/sub 3/ and Fe/sub 2/O/sub 3/). This presentation discusses the approach for assembling these two classes of nanostructured materials to obtain more complex hybrid architectures.
