Self-assembly of gold nanorods

Article Abstract:

Self-assembly of gold nanorods (NRs) with aspect ratio of ~4.6 (12 nm in diameter and 50-60 nm in length) is studied using transmission electron microscopy (TEM). The results reveal that under appropriate conditions such as nanoparticle concentration, solvent evaporation, narrow size distribution, ionic strength, and surfactant concentration of the parent solution, gold nanorods assemble into one-, two-, and three dimensional structural, thus proving that it is possible to generate self-assemblies of gold nanorods.

Laser-Induced shape changes of colloidal gold nanorods using femtosecond and nanosecond laser pulses

Article Abstract:

Gold nanorods is found to change their shape after excitation with intense pulsed laser irradiation. The result indicate that the influence of the laser pulse width on the photothermal treatment of gold nanorods are in very good agreement with the laser ablation studies on bulk metal films.

Surface reconstruction of the unstable {110} surface in gold nanorods

Article Abstract:

High-resolution transmission electron microscopy has been used to investigate gold nanorods prepared electrochemically and capped in micelles. The {100} surface shows atom-height surface steps, while the {110} surface has the missing-row reconstruction.
