Optical tweezer magnetic levitation observation device

Abstract

The invention provides an optical tweezers magnetic levitation observation device which comprises a main body, a supporting plate, a support, a laser generator, a placement frame, a levitation block,a microscopic digital camera and a display screen, a through hole is formed in the center of the main body, a mounting groove is formed in the main body, and a main body coil is fixedly mounted in themounting groove; a support is welded to one side of the top of the main body. According to the optical tweezer magnetic levitation observation device, the magnitude of current in the main body coil can be controlled through the controller, so that the magnetic field intensity of the main body coil is controlled, the height of the levitation block can be adjusted, and the position of a formed optical trap is adjusted through the eyepiece; bacteria or microorganisms can suspend, the suspension block can be conveniently installed and supported through the containing frame, the suspended bacteriaand microorganisms can be conveniently observed through the microscopic digital camera and the display screen, heat dissipation is conveniently conducted on the main body coil through the ventilationopenings and the heat dissipation holes, and the failure rate is reduced.

Description

technical field [0001] The invention relates to the technical field of optical tweezers, in particular to an optical tweezers magnetic levitation observation device. Background technique [0002] Optical tweezers are optical traps using chip-based photon resonance capture technology, which can manipulate and capture nanometer to micron-scale examples. Optical traps can be formed by laser aggregation, and tiny objects are trapped in optical traps by light pressure. Moving the light beam makes tiny objects move with the optical trap, so that tiny objects, such as viruses, bacteria, and intracellular organelles and cellular components, can be displaced or operated under a microscope. Optical tweezers that capture tiny particles are a A special light field, when this light field interacts with an object, the entire object is affected by the light to achieve the effect of being clamped, and then the object can be moved by moving the light beam. The existing optical tweezers have ...

[0002] Optical tweezers are optical traps using chip-based photon resonance capture technology, which can manipulate and capture nanometer to micron-scale examples. Optical traps can be formed by laser aggregation, and tiny objects are trapped in optical traps by light pressure. Moving the light beam makes tiny objects move with the optical trap, so that tiny objects, such as viruses, bacteria, and intracellular organelles and cellular components, can be displaced or operated under a microscope. Optical tweezers that capture tiny particles are a A special light field, when this light field interacts with an object, the entire object is affected by the light to achieve the effect of being clamped, and then the object can be moved by moving the light beam. The existing optical tweezers have complex structures and are inconvenient to perform Observed
