Seeded Growth Synthesis of Uniform Gold Nanoparticles with Diameters of 15−300 nm
Abstract
In this work, we present a simple seeded growth approach to obtain gold nanoparticles over a large range of sizes. The method produces particles with uniform spherical shape and narrow size distributions. Using ascorbic acid as a reductant and sodium citrate as stabilizer we utilize biocompatible and easy to exchange substances. The investigation of the growth process via TEM measurements revealed the formation of small gold clusters on the surface of the seeds, which subsequently grow and result in a “blackberry-like” intermediate shape of the gold nanoparticles. Applying heat caused an intraparticle ripening process, which finally lead to a smooth spherical particle shape. Furthermore, the optical properties of the resulting gold sols are discussed in the light of Mie theory and an influence of the polydispersity was found for large particles.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
