Preparation of Gold Colloids with UV Irradiation Using Dendrimers as Stabilizer
Abstract
Au colloids have been prepared by reduction of metal salt with UV irradiation in the presence of dendrimers. Poly(amidoamine) dendrimers with surface amino groups for generations 0, 1, 2, 3, 4, and 5 (G0−5) have been used. The average particle sizes decrease with an increase of concentration of surface amino group of the dendrimers. In particular, Au colloids with a diameter less than 1 nm are obtained in the presence of the later generation dendrimers(G3−5) at above the molar ratio of surface amino group of dendrimer/HAuCl 4 (4:1). These concentrations are extremely small compared with that of other polymers, indicating that the dendrimers have an effective protective action for the formation of Au colloids.

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.
