Abstract

This talk describes recent developments in the synthesis and characterization of semiconductor and metal nanoparticles using a preparative flow system. Results on the growth kinetics and the control of size, shape and surface chemistry will be addressed. We report on the non-covalent attachment of nanoparticles to carbon nanotubes and shape transformations induced by the attachment. Examples of applications in the area of optoelectronics, photovoltatics and catalysis will be given. We discuss the use of nanoparticles for biological and medical applications which includes a robust coating with biocompatible polymers and embedding nanoparticles in polymer vesicles. We also present experiments on the toxicity of nanoparticles using advanced optical microscopy for in-vitro cell culture studies. Examples on the improvement of magnetic resonance imaging using tailored superparamagnetic nanoparticles are given.
