Technologies for acoustoelectronic nanotweezing

Abstract

Technologies for acoustoelectronic manipulation of micro/nano particles include a system having a piezoelectric substrate coupled to one or more acoustic transducers and a fluid layer positioned above the substrate. Micro/nano particles are introduced to the fluid, which can be in the form of a droplet or in a confined channel, and a signal is applied to the acoustic transducer. One or more parameters of the signal are varied after introducing the micro/nano particles into the fluid. The parameters may include amplitude, frequency, or phase of the signal. The system may include one or more acoustic transducers. Multiple signals may be applied to the acoustic transducers. Wave superposition of acoustic waves in the substrate manipulates micro/nano particles in the fluid. The nanoparticles may include carbon nanotubes, nanowires, nanofibers, graphene flakes, quantum dots, SERS probes, exosomes, vesicles, DNA, RNA, antibodies, antigens, macromolecules, or proteins.
