  • Technique for three-dimensional nanoprinting
    Patent number: 10751933
    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.
    Type: Grant
