12 p, 1.0 MB One-Pot Synthesis of Cationic Gold Nanoparticles by Differential Reduction / Sperling, Ralph A. (Institut Català de Nanociència i Nanotecnologia) ; García Fernández, Lorena (Institut Català de Nanociència i Nanotecnologia) ; Ojea-Jiménez, Isaac (Institut Català de Nanociència i Nanotecnologia) ; Piella, Jordi (Institut Català de Nanociència i Nanotecnologia) ; Gómez Bastús, Neus (Institut Català de Nanociència i Nanotecnologia) ; Puntes, Víctor (Institut Català de Nanociència i Nanotecnologia)
The size-controlled synthesis of cationic particles by differential reduction of HAuCl precursor in the presence of NaBH and 1-aminoundecane-12-thiol (AUT) is reported. The number of seed particles is determined by the fraction of the initially Au precursor reduced by NaBH present in the reaction mixture, which are then grown larger by the AUT, acting as both weak reducing agent and stabilizing surfactant.

18 p, 1.2 MB Modeling the Optical Responses of Noble Metal Nanoparticles Subjected to Physicochemical Transformations in Physiological Environments : Aggregation, Dissolution and Oxidation / Piella, Jordi (Institut Català de Nanociència i Nanotecnologia) ; Gómez Bastús, Neus (Institut Català de Nanociència i Nanotecnologia) ; Puntes, Víctor (Institut Català de Nanociència i Nanotecnologia)
Herein, we study how optical properties of colloidal dispersions of noble metal nanoparticles (Au and Ag) are affected by processes such as aggregation and oxidative dissolution. The optical contributions of these processes to the extinction spectra in the UV-vis region are often overlapped, making difficult its interpretation. [...]
