Abstract | The ability to print and manipulate nanoscale objects affects diverse fields as materials science, nanotechnology, and biomedicine. Although many scientists and engineers have continually developed clever and high-precision techniques, new methods are still in great demand for different materials and geometries. Here I will present nanopipette-assisted methods for single particle manipulation and 3D printing: 1) scanning-aperture electrostatic tweezers and 2) meniscus-guided 3D printing. First, I will discuss an interesting finding that surface charges of glass nanopipettes can be used to pick and place single charged nanoparticles at will in a fluid. This technique, scanning-aperture electrostatic trap, enables contact-free, size-independent trapping of very small single nanoparticles. The application to fundamental study on plasmonics will also be discussed. Second, I will discuss a meniscus-guided 3D printing method that exploits a mechanically flexible liquid meniscus formed at a pipette-substrate gap to 3D print functional materials at the micro/nanoscale. This technique can be successfully applied to various materials such as polymers, graphene, metals, CNTs, and soft microbubbles. |
