Abstract
A preferred method of the invention separates metallic or charged nanostructures in solution. In preferred embodiments, metal and semiconducting nanostructures are separated in solution with use of a net Lorentz force applied to metallic or conductive nanostructures. In other embodiments, charged nanostructures are separated from other nanostructures in solution. The charge can be applied to semiconducting or insulating nanostructures of a predetermined size by application of appropriate radiation. The method is conducted on dispersed nanostructures suspended in solution in a vessel. The net Lorentz force to metallic, conductive or charged nanostructures within the solution moves the metallic, conductive or charged nanostructures toward a common volume in a portion of the vessel. Extraction of the common volume provides solution with a high ratio of the metallic, conductive or charged nanostructures. The solution left behind has a high ratio of semiconducting or insulating nanostructures. That solution can also be recovered.
