Nucleation and Growth of Goldnanoparticles — •Felix Bourier, Tobias Redder, Christian Strelow, and Alf Mews — Universität Hamburg, Hamburg, Deutschland

Although inorganic nanocrystals are already used for large-scale technical and biomedical applications such as, biomarkers and drug delivery systems, their wet chemical production is still based on mainly empirical protocols. An understanding of nanocrystal formation exceeding the far too simplified classical models of nucleation and growth is still lacking.
Tracking the reduction of a gold precursor in toluene followed by the formation of nanoclusters, which then grow into particles should give better insights into the underlying mechanisms. This is achieved by combining experimental and simulated data with the use of a numerical aproached based on a set of rate equations.
