Description
Technical Field
The invention relates to the field of machinery, in particular to a magnetic field control system for driving a magnetic micro-nano robot.
Background
The synthetic micro-nano robot can provide power sources by different energy sources. Most commonly, micro-nano motors can be autonomously propelled in a directed manner by means of generated microbubbles (e.g., O2, H2, CO2) or molecular concentration gradients based on local chemical energy conversion.
However, fuel degradation is caused by the use of chemical sources outside the chemically powered micro-nano robot, which greatly hinders its application in biological environments. Biocompatible-based fuels and various other types of propulsion mechanisms have been extensively explored today, including enzymatic breakdown of glucose or urea, reaction of reactive metals with water or acids, and the like. Fuel-free synthetic micro-nano-robots, driven by an external field (e.g., optical, magnetic, ultrasonic, or electric), operate efficiently in bio-related environments (typically with high viscosity and high ionic strength). Because the motion of the micro-nano robot is controlled according to needs, the micro-nano robot has the advantages of long service life, good biocompatibility and the like, and has great potential in the research aspect of micro-nano robots in organisms.
The three-dimensional magnetic field control system is a complete set of control system which can generate a high-precision three-dimensional magnetic field, accurately drive a magnetically-driven structure in the device and consists of a Helmholtz coil, an observation system and magnetic field control software. The system can generate a high-precision three-dimensional magnetic field and accurately drive magnetic substances in the magnetic field, has a huge application prospect in the field of biomedicine, and is a current international research hotspot. Typically, to construct such a system, the entire design is required from the Helmholtz coil, to the microscope, and then to the control software. In some application scenarios in a laboratory, however, it is too expensive to design an integrated magnetic field control system.
Three-dimensional magnetic field control systems have been a hotspot in the research fields of biomedicine and the like. However, these fields require that the particles or magnetically-actuatable structures driven by magnetic fields be at a microscopic scale and require observation in conjunction with a microscope. At present, the key to constructing a three-dimensional magnetic field manipulation system is the combination of the helmholtz coil and the microscope and the duration of the coil operation. Many of the coils today are large, bulky and do not integrate well with the microscope. The strength of the magnetic field decays very rapidly, usually by too far from the center of observation. Meanwhile, as the coil generates a lot of heat during working, the energy conversion efficiency is lowered, the magnetic field intensity is correspondingly reduced, the energy consumption is increased, and the system can not work continuously even.
