Problems solved by technology

[0004] For the acoustic tweezers control technology, because the acoustic potential well has a three-dimensional limitation capability, the acoustic tweezers device can achieve precise three-dimensional movement, but its control accuracy for the rotation of the operating object at the current position is not high
In addition, for the magnetic tweezers control technology, although the precision of rotating the operation object at the current position is very high, and the rotation direction is not limited, but when a single magnetic tweezers device controls the movement of the operation object, it cannot achieve precise movement, and must With high-response feedback control, it is difficult to control the precise movement and precise rotation of the object through the magnetic tweezers control technology, and the structure is complex

Embodiment Construction

[0040] The following will clearly and completely describe the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0041] Acoustic tweezers use ultrasonic transducers (or transducers and reflectors) facing each other, transducers combined with holographic acoustic lenses, or phased ultrasonic arrays to form an acoustic potential well in space, and limit the manipulated object to the sound trap. among. Therefore, the motion control of the object trapped in the sound trap can be realized by moving the ultrasonic probe or electronically deflecting the position of the sound trap by modulating the vibrat...

Abstract

The invention provides a sound tweezers and magnetic tweezers combined control device and control method, and the device comprises a sound tweezers assembly which is used for forming a control sound field in a control region, and controlling a control object to move in the control region; the magnetic tweezers assembly is located on one side of the sound tweezers assembly and used for forming a control magnetic field in the control area and controlling the control object to rotate at the current position; wherein the control object has magnetism. According to the control device and the control method provided by the technical scheme of the invention, non-contact accurate control on the motion of the control object is realized.

Description

technical field [0001] The invention relates to the field of manipulation of micro-nano particles, and more specifically, relates to a manipulation device and a manipulation method combining acoustic tweezers and magnetic tweezers. Background technique [0002] Acoustic tweezers and magnetic tweezers, as two emerging non-contact manipulation technologies, have significant application potential in biomedical research fields such as noninvasive surgery, targeted therapy, and cell control. [0003] Acoustic tweezers form an acoustic potential well in space, confine the manipulated object in the sound trap, and realize the motion control of the object trapped in the sound trap by deflecting the position of the sound trap. Magnetic tweezers control the movement of a magnetic operating object by changing the magnetic field. When the operating object is inconsistent with the direction of the applied magnetic field, the operating object will receive a rotational torque related to th...
