Abstract: The present invention relates to hollow nanocoils having a three-dimensional helical structure in the form of a hollow tube and a method of manufacturing the same.
The present invention provides a method of synthesizing metal nanocoils into inorganic hollow nanocoils using the galvanic replacement reaction and an electrochemical reaction including the Kirkendall effect. The inorganic hollow nanocoil structure body of the present invention can be applied to various fields such as sensors, catalysts, batteries, or gene delivery and therapy using a large surface area.

Abstract: Disclosed is a technical idea of forming ruthenium and ruthenium-cobalt alloy nanowires having various diameters using electroplating. More particularly, a technology of forming ruthenium and ruthenium-cobalt alloy nanowires on a porous template, on pores of which nanotubes are deposited using atomic layer deposition (ALD), using electroplating, and annealing the ruthenium and ruthenium-cobalt alloy nanowires to form ruthenium-cobalt alloy nanowires having various diameters.
