Device and method for coagulation and manipulation of nanomaterials using high-frequency ultrasonic single-beam acoustic tweezers
[0001] The present invention relates to nanomaterial coagulation and manipulation control, and more particularly, to a device and method for nanomaterial coagulation and manipulation using high-frequency ultrasonic single beam acoustic tweezers that can coagulate and manipulate nanomaterials using single beam acoustic tweezers (SBAT) that irradiate single beam sound using an ultrasonic transducer.
[0002] Nanoparticles are particles with a size ranging from 1 nm to 100 nm.
[0003] Nanoparticles have a relatively large surface area compared to their volume, and because of this characteristic, they exhibit electrical, optical, and magnetic properties that are different from those of general bulk materials.
[0004] Recently, optical devices, light-emitting devices, and metal catalysts manufactured by applying the characteristics of these nanoparticles are widely distributed in the market.
[0005] The biggest problem in using these nanoparticles in various devices is the aggregation of the nanoparticles.
[0006] Efforts are continuously being made to control the aggregation of these nanoparticles, as this aggregation degrades the electrical, optical, and magnetic properties of the nanoparticles, ultimately degrading the quality of the device.
[0007] In this way, as the particle size decreases to the nanoscale, the proportion of particles present on the surface increases, the surface free energy increases, and the curvature of the particle surface affects the intermolecular distance and molecular structure.
[0008] In particular, mechanical dispersion manipulations such as ultrasound and stirring, which are effective for sub-micron particles, are largely ineffective for nanoparticles.
[0009] Because of the limitations described above, in order to obtain highly dispersible nanoparticles, it is necessary to control aggregation by simultaneously performing dispersion manipulation at the particle generation stage.
[0010] Therefore, the development of new technologies that enable the aggregation and manipulation of nano-sized fine materials is required.
[0011] The present invention is intended to solve the problems of the conventional nano-material coagulation and manipulation control technology, and provides a device and method for coagulating and manipulating nano-materials using high-frequency ultrasonic single beam acoustic tweezers (SBAT), which can coagulate and manipulate nano-sized fine materials using single beam acoustic tweezers that irradiate single beam sound using an ultrasonic transducer.
[0012] The purpose of the present invention is to provide a device and method for coagulating and manipulating nanomaterials using a high-frequency ultrasonic single beam acoustic tweezers, which enable effective control and creation of nano-scale micromaterials by coagulating or manipulating particles using the acoustic radiation force (ARF) generated when a single ultrasonic beam generated from a single element transducer in the high-frequency ultrasonic region is refracted by a particle surface and the direction of the beam changes.
[0013] The purpose of the present invention is to provide a device and method for coagulating and manipulating nanomaterials using high-frequency ultrasonic single beam acoustic tweezers (SBAT), which generate a single beam to cause acoustic radiation force (ARF) to be generated on the surface of particles of fine materials, thereby coagulating or manipulating particles, thereby adjusting the force applied to the material in real time to immediately change the position or arrangement of the material.
[0014] The present invention aims to provide a device and method for coagulating and manipulating nanomaterials using high-frequency ultrasonic single beam acoustic tweezers, which can be usefully used in the field of nanotechnology by using single beam acoustic tweezers (SBAT), which have a simple setup, low equipment complexity, and provide high precision in manipulating materials.
[0015] The present invention aims to provide a device and method for coagulating and manipulating nanomaterials using high-frequency ultrasonic single beam acoustic tweezers, which can minimize the risk of damage or contamination of nanomaterials and can manipulate materials of various sizes and types by using single beam acoustic tweezers (SBAT) that have non-invasive characteristics that operate without physical contact with the material to be manipulated, so that they can be applied to various nano-application fields.

[0053] FIG. 4 is a flow chart illustrating a method for coagulating and manipulating nanomaterials using high-frequency ultrasonic single beam acoustic tweezers according to the present invention.
[0054] First, adjust the tilt so that the ultrasonic sensor (transducer) is parallel to the bottom of the petri dish. (S401)
[0055] The inclination of the ultrasonic sensor is a key factor affecting the force transmitted to the nanomaterial. When the nanomaterial and the sensor are aligned as parallel as possible, maximum force is transmitted to the nanomaterial.
[0056] Next, the ultrasonic sensor focus is positioned so that it aligns with the microscope focus and the bottom of the petri dish. (S402)
[0057] Nanomaterials must be positioned precisely at the focus of the ultrasonic sensor to effectively aggregate and manipulate them. Furthermore, the microscope's focus must be precisely adjusted to observe the aggregation and manipulation of nanomaterials.
[0058] And a signal is provided to the ultrasonic sensor through a function generator and amplifier. (S403)
[0059] Each ultrasonic sensor used changes the power of the ultrasonic beam according to various information input from the connected function generator.
[0060] Therefore, information appropriate for each sensor is input to the function generator, enabling effective aggregation and manipulation of nanomaterials. Nanomaterials are aggregated and manipulated by the ultrasonic beam generated in this manner.
[0061] Next, a single beam acoustic tweezers is used to control and manipulate nanomaterials by using the acoustic radiation force (ARF) generated when an ultrasonic beam is irradiated and the direction of the beam changes due to refraction by the surface of the nanomaterial particles (S404).
[0062] And the result of the cohesion operation is analyzed to calculate the ultrasonic sensor supply signal value and provide a signal to the ultrasonic sensor (S405).
[0063] The device and method for coagulating and manipulating nanomaterials using a high-frequency ultrasonic single beam acoustic tweezers according to the present invention described above utilizes the generation of acoustic radiation force (ARF) when a single ultrasonic beam generated from a single element transducer in the high-frequency ultrasonic range is refracted by a particle surface and the direction of the beam changes, thereby coagulating or manipulating particles, thereby enabling effective control and creation of nano-sized micromaterials.
