Les propriétés inattendues des nanoparticules d'or font que le contrôle de leur taille, de leur forme et/ou de leur morphologie devient essentiel pour une application ciblée. Des formes variées de nanoparticules en solution colloïdale ont été synthétisées. L'analyse de ces solutions par spectroscopie UV-Visible montre que les nanoparticules anisotropes ont deux bandes plasmoniques. Aussi, le potentiel zêta mesuré révèle que les solutions sont stables dans les conditions d'étude. La caractérisation par la microscopie électronique en transmission a permis d'observer que leur surface présente différentes orientations cristallographiques. Le dépôt sous potentiel du plomb par voltammétrie cyclique a révélé les sites cristallographiques à la surf...
