Abstract

We have demonstrated glutathione- and cysteine-induced transverse overgrowth on gold nanorods. In aqueous solutions, glutathione and cysteine are preferentially bound to the ends of gold nanorods that are stabilized by a cationic surfactant bilayer. This preferential end binding blocks the growth of the nanorods in the longitudinal direction completely and allows for the growth only in the transverse direction. As a result, the diameters of the nanorods become larger and larger while their lengths remain unchanged, as more and more gold precursor is supplied. In addition, the shape of the nanorods undergoes a gradual change from rods, peanuts, and truncated octahedra to faceted spheres during overgrowth. We believe that this transverse overgrowth provides an alternative means for tailoring the longitudinal plasmon wavelengths and extinction cross sections of gold nanoparticles and will therefore facilitate their use in optics, optoelectronics, and biotechnology.

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.
