MANUFACTURING METHOD OF GOLD NANOPARTICLE WITH WELL-DEFINED SIZE THROUGH WIRE EXPLOSION IN LIQUID

摘要

The present invention relates to a manufacturing method of a gold nanoparticle through wire explosion in a liquid and, more specifically, relates to a manufacturing method of a gold nanoparticle, which comprises the following steps of: (1) preparing a gold wire of which a diameter and a supplied length are different; (2) preparing a liquid to perform wire explosion; (3) preparing the wire explosion by supplying voltage to the wire; and (4) performing the wire explosion from ten times to one hundred times. As stated above, according to the present invention, provided is a gold nanoparticle that is not harmful for a human body and has a well-defined size with high yield. Moreover, the manufacturing method of a gold nanoparticle can be utilized for a bio-field such as disease and microorganism analysis, wherein the gold nanoparticle has not been applied to the bio-field.
