Chemical-energy-driven nano motor, power providing method thereof and nano robot

Abstract

The invention belongs to the field of nanotechnology, and particularly relates to a chemical-energy-driven nano motor, a power providing method thereof and a nano robot. The nano motor comprises a shell and metallic sodium; the upper portion inside the shell is provided with an oil layer, and the lower portion is provided with a water layer; an opening is formed in the upper portion of the shell,and the opening is covered with a semi-permeable membrane allowing gas to pass through; and the metallic sodium is detachably arranged on the inner wall of the upper portion of the shell, and the density of the metallic sodium is greater than that of the oil layer. According to the nano motor, a large amount of hydrogen released through reaction between the metallic sodium and water can be used asdriving force of the nano motor so that the motion rate of the nano robot assembled with the nano motor can be well guaranteed; and meanwhile, according to the chemical properties of the sodium element, the nano motor adopts different liquids to construct a double-layer reaction space, the reaction rate of sodium and water can be reasonably controlled by adjusting the ratio of the oil layer to the water layer, the safety coefficient of the nano motor in the operation process is improved, and the braking duration of the nano motor is effectively prolonged.

Description

technical field [0001] The invention belongs to the field of nano science and technology, and in particular relates to a chemical energy-driven nano engine, a method for providing power, and a nano robot. Background technique [0002] Nano-robots are one of the most popular researches after people enter the microscopic field. The rise of nano-robots will provide great convenience for human beings and solve a large number of medical problems. In order to provide sufficient kinetic energy for the movement of nanorobots and ensure their safe and stable movement, people have explored their key components—nanomotors—in many fields such as physical chemistry. [0003] At present, researches on the driving of micro-nano motors at home and abroad mainly include chemical energy driving, external field driving, and laser energy supply. Among them, the laser energy supply is to use the laser to heat the nano-engine, and use the principle of storing and releasing energy during the aggr...

Problems solved by technology

[0004] At present, a kind of nanomotor is prepared by cathode electrochemical reaction 2H 2 o 2 =2H 2 O+O 2 ↑, decomposes into water in the permanganate ion solution, releases oxygen at the same time, and generates forward propulsion through gas release in the pipe-type micro-nano engine, but due to the use of MnO 2 As a catalyst, its activity and catalytic efficiency are limited, so the decomposition rate of hydrogen peroxide is very slow, and the kinetic energy provided is relatively small, which cannot guarantee the energy required by the nanorobot during the movement process.
