Abstract

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. The nano-engine provided by the present invention includes: a housing, the upper part of the housing is an oil layer, and the lower part is a water layer; the upper part of the housing is provided with an opening, and the opening is covered with a semi-permeable membrane that allows gas to pass through; Sodium metal, the density of sodium metal > oil layer. The nanometer engine provided by the invention can use the metal sodium to react with water to release a large amount of hydrogen as the driving force of the nanometer engine, and can well ensure the movement speed of the nanometer robot equipped with the nanometer engine. At the same time, according to the chemical properties of the sodium element, the nano-engine provided by the invention uses different liquids to construct a double-layer reaction space. By adjusting the ratio of the oil layer and the water layer, the reaction rate of sodium and water can be reasonably controlled, and the efficiency of the nano-engine operation process can be improved. The safety factor is effective to prolong the braking time of the nano-engine.

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.
