Method of producing gold powders and the use thereof

Abstract

The present invention provides a method for producing gold powders. The method comprises providing a vacuum environment and using an electric target to vaporize a source gold to produce gold powders. A spinner is operated and provides ultrasonic vibration effects. The spinner has cooling devices on the inner wall of spinner to cool down the up-rising gold powers and reduce the adhesive force of the gold powders. A static-electronic collector is then used to collect the gold powders.

What is claimed is:  
     
         1 . A method for producing gold powders, comprising: 
 providing a vacuum environment;    using an electric target to vaporize a source gold to produce gold powders;    operating a spinner that provides ultrasonic vibration effects, the spinner having cooling devices on the inner wall of spinner to cool down the up-rising gold powers and reduce the adhesive force of the gold powders;    applying a static-electronic collector to collect the gold powders.    
     
     
         2 . The method of  claim 1 , wherein the gold powders have sizes of about 1 nanometer to 1 micrometers for providing safe medical use in resisting tumors and/or strengthen immune systems.
