Abstract
An apparatus and process for creating uniformly sized, spherical nanoparticles from a solid target. The solid target surface is ablated to create an ejecta event containing nanoparticles moving away from the target surface. Ablation may be performed by laser or electrostatic discharge. At least one continuous planar electromagnetic field is placed in front of the solid target surface being ablated. The electromagnetic field manipulates at least a portion of the nanoparticles as they move away from the target surface and pass through the electromagnetic field to increase size and spherical shape uniformity of the nanoparticles. The manipulated nanoparticles are collected as a stable suspension in a fluid.
