▎ 摘　　要

NOVELTY - The method involves introducing nanoparticles into a fluid layer positioned over a surface of a piezoelectric substrate that comprises a y-cut, and 41 degrees rotated lithium niobate crystal. A signal is applied to an acoustic transducer set coupled to a surface of the substrate and spaced apart from the fluid layer. A parameter of the signal is varied after introducing the nanoparticles into the fluid layer. A standing acoustic wave is created in the piezoelectric substrate, where the standing wave is in-plane relative to the surface of the piezoelectric substrate. USE - Method for acoustoelectronic manipulation of nanoparticles such as carbon nanotubes, nanowires, nanofibers, graphene flakes, quantum dots, surface-enhanced Raman scattering (SERS) probes, exosomes, vesicles, DNA, RNA, antibodies, antigens, macromolecules, and proteins (all claimed). ADVANTAGE - The method enables combining light-induced dielectrophoresis with local convective vortices by acoustoelectronic tweezers to achieve nano-scale trapping with lower field intensity and manipulating the nanoparticles with high spatial resolution and single-particle maneuverability. The acoustic transducer set is positioned over the surface of the piezoelectric substrate and spaced apart from the fluid layer, and the parameter of the signal is varied after introducing the nanoparticles into fluid layer, thus enabling precise manipulation of nano-objects on a large scale to enable fabrication of materials and devices with tunable optical, electromagnetic, and mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a system for acoustoelectronic manipulation of nanoparticles.
