Method and apparatus for manufacturing colloidal rod particles

Abstract

Segmented nanoparticles are manufactured according to different methods and in various apparatuses.

What is claimed is:  
     
         1 . An apparatus for manufacturing a nanoparticle, comprising: 
 a plating solution chamber;    a defined-pore size template;    means for applying a current to cause electrochemical deposition within pores of said template;    means for agitating solution within said plating solution chamber; and    means for controlling the temperature of said plating solution chamber.    
     
     
         2 . The apparatus of claim 1  wherein said template is selected from the group consisting of an Al 2 O 3  membrane, a photolithographically prepared template, a porous polycarbonate membrane, a zeolite and a block copolymer.  
     
     
         3 . An apparatus for simultaneously manufacturing a plurality of different types of nanoparticles, comprising: 
 a plating solution chamber;    a plurality of template regions;    means for selectively applying an electrical current to said template regions; and    control means for controlling deposition into said template regions.    
     
     
         4 . The apparatus of  claim 3  wherein said template regions are selected from the group consisting of an Al 2 O 3  membrane, a photolithographically prepared template, a porous polycarbonate membrane, a zeolite and a block copolymer.
