▎ 摘　　要

NOVELTY - Noble metal nanostructures preparation involves placing noble metal sheet into nano graphene oxide solution, and then performing pulsed laser ablation of the noble metal to obtain noble metal nanostructures. USE - Method for preparing noble metal nanostructures for use in biomedical applications (claimed). ADVANTAGE - The method prepares the noble metal nanostructures in a simple and cost-effective manner with uniform structure and appearance, controllable particle diameter, improved dispersibility, and good biologic compatibility without residual chemistry. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic transmission electron microscopic image of the gold nanometer structure.
