Abstract

The disclosed embodiments provide a system that forms a three-dimensional (3D) nanostructure through 3D printing. During operation, the system performs a 3D printing operation that uses multiple passes of a scanning probe microscope (SPM) tip to deliver an ink to form the 3D nanostructure, wherein the ink includes both a positively charged polyelectrolyte (PE) and a negatively charged PE. While delivering the ink, the SPM tip is loaded with the ink and moved to a target location to deposit the ink. Finally, after the multiple passes are complete, the system cures the 3D nanostructure to remove excess positive or negative charges from the 3D nanostructure.
