Detailed Description
The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following.
As shown in fig. 1 to 3, a nano robot for precisely treating sewage comprises a bionic body 1 and a plurality of probes 2; wherein, the bionic body 1 is internally provided with a nano motor 7, and the nano motor 7 is internally provided with hydrogen peroxide fuel; a plurality of probes 2 are connected on the head of the bionic body 1.
In the scheme, the probe 2 comprises a long chain 3 formed by self-assembled alkyl mercaptan and a polar head functional group 4 of the alkyl mercaptan, and the long chain and the polar head functional group are connected to the head of the bionic body 1. Wherein, the polar head functional group 4 is selected according to different sewage conditions, and the outer layer comprises but is not limited to the following branched chain layers: modifying the Au/Ni/pt branch chain layer for removing oily liquid in the sewage; concanavalin A grafting for cleaning escherichia coli; modifying Mg-Au Janu for cleaning organic matters; modifying Pt-Fe for cleaning dye wastewater; modifying the surface modified thrombin-ATP for protein clearance; modifying specific single-stranded DNA for cleaning nucleic acid; the high water-solubility glucosamine contains javanine/rhodamine group, and is used for complexing mercury ions. Of course, corresponding branched chain layers can also be arranged on the surface of the bionic body 1.
In this embodiment, the head of the biomimetic body 1 is a tapered head 9, a Pt catalyst layer is disposed on the rear end face of the tapered head 8, and hydrogen peroxide in the nanomotor 7 is led to the tapered head 9 through the tube 8. The hydrogen peroxide fuel is conveyed to the Pt catalyst layer through the pipe barrel 8 to be catalytically decomposed, and forward force is formed on the conical head 9 when oxygen and hydrogen are released after the catalytic decomposition, so that traction is formed.
Further, the cone head 8 comprises 4 layers laminated together; the catalyst layer is a Pt catalyst layer, the Fe-Ni magnetic layer, the Ti inert layer and the Au thin layer are arranged from inside to outside in sequence.
Furthermore, the Pt catalyst layer is doped with carbon nanotubes, so that the speed is improved. Specifically, the internal pt surface of the tubular micromotor catalytically decomposes the hydrogen peroxide fuel, and the generated oxygen bubbles generate continuous propulsive force; the motor is pushed to move forwards; peroxide fuel enters the micro taper pipe through a small opening at the front end of the pipe, and a platinum catalyst layer in the micro pipe cavity is excited; the live hydrogen oxide fuel decomposes to produce oxygen and subsequently nucleates to form bubbles which, once detached from the exit behind the motor, the micro-motor maintains the original shape of the tube without bubbles to cater for the next cycle of motion (repeated to allow the robot to move at low reynolds numbers).
And furthermore, a flow-out hole is formed at the front end of the middle part of the bionic body 1, the conical head 9 is larger than the front end of the middle part of the bionic body 1, and the hydrogen peroxide barrel cylinder 8 in the nano motor 7 is discharged and then contacts with the Pt catalytic layer on the conical head 8 through the flow-out hole.
In this embodiment, the middle surface of the bionic body 11 is further provided with a decorative joint which can be used for selective loading and transporting of goods, the corresponding function of selective loading is achieved, and directional transportation is performed after loading and assembling.
In order to control the direction, a magnetic section or layer is also embedded in the bionic body 1, and then the bionic body is realized by combining the guidance of an external magnetic field. Shorter metal (nickel) segments with magnetic properties, which can be magnetized in a transverse external magnetic field perpendicular to the long axis of the nanowires, are embedded in the nanomotor. The magnetic field controls the motion direction, so that the nano motor can be controlled to move along a preset track. The body is precisely guided and steered by a magnetic field along a preset track, so that the nano motor directionally moves along a preset path in a complex micro-channel network, and the magnetic sorting outside the nodes of the microchip is realized. By utilizing the magnetic orientation, the influence of various experimental parameters on the speed of the motor is better visualized and compared.
And the bionic body 1 is arranged asymmetrically. Due to the existence of the platinum-gold section, when the hydrogen peroxide is contacted with the platinum-gold section on the bionic body 1, the decomposition degrees of different positions are different, so that the number of the produced bubbles is different, and the force is unbalanced, thereby enabling the bionic body 1 to rotate.
In this example, to increase the speed, hydrazine or silver ions are added to the peroxide solution to increase the speed and driving force of the nano-or motor. The speed increased from 5.0pum/s to 94.0pum/s, which is a significant 20-fold increase.
Optionally, the nano robot for precisely treating sewage is designed to open and close the pipe barrel 8, and the nano motor 7 is led to the conical head 9 through the pipe barrel 8 through the outflow hole.
Specifically, there are two design modes, one is: the front end of the pipe barrel 8 is sealed by a material containing azobenzene, and the opening and closing of the pipe barrel 8 are realized by irradiating the azobenzene by ultraviolet rays, so that the opening and closing of the hydrogen peroxide conveyed by the pipe barrel 8 are controlled, and the guide control is realized.
The other is as follows: the pipe barrel 8 is provided with a plurality of release ports, and molecular shuttles are arranged at the release ports; the opening and closing of the release port are realized through the opening and closing of the molecular shuttle, the opening and closing of the hydrogen peroxide conveyed by the pipe barrel 8 are realized, and the guide control of the conical head 9 is realized, so that whether the nano robot is driven to act or not is controlled.
Specifically, the molecular shuttle includes a ring portion, a straight line portion passing through the ring portion, and both ends of the straight line portion having blocking groups; one blocking group of the straight line part is positioned in the release opening of the tube 8, and the other end of the other blocking group is provided with a catalytic reaction cavity which is filled with ATP fuel and hexokinase. When the molecular shuttle works: under the irradiation of ultraviolet rays, ATP fuel can be combined and hydrolyzed, and then a corresponding blocking group can be pushed, so that the straight line part pushes the blocking group at the other end to act; in the absence of UV light, hexokinase degrades ATP enzymes, and the linear portion moves back.
It should be noted that, in order to allow the ultraviolet rays to be smoothly irradiated, a transparent material is disposed at a corresponding position.
Optionally, a nanometer robot for precisely treating sewage is designed for driving the middle part of the bionic body 1.
Specifically, a gear 5 is arranged on the outer surface of the middle part of the bionic body 1, and a Pt layer is deposited on the same clockwise side/anticlockwise side of each tooth of the gear 5. When the hydrogen peroxide fuel from the bionic body 1 is released, the hydrogen peroxide fuel is also contained in the water, and when the Pt layer on the gear 5 is contacted with the hydrogen peroxide, the hydrogen peroxide is decomposed, so that the rotation of the gear 5 is realized.
Optionally, the tail of the bionic body 1 is designed by another type of nano robot for precisely treating sewage, as shown in fig. 2.
Specifically, the tail of the bionic body 1 is provided with polydimethylsiloxane, and the tail of the bionic body is also connected with a bionic tail. The tail part of the bionic body 1 is also provided with a surface layer containing azobenzene, and the surface layer seals polydimethylsiloxane inside; the bionic tail is provided with a Pt layer.
When the bionic tail is in work, under the irradiation of ultraviolet light, the surface layer containing azobenzene is opened, and polydimethylsiloxane is released, so that the polydimethylsiloxane and the Pt layer at the bionic tail are subjected to catalytic reaction to form reverse impact; under the irradiation of visible light, the surface layer containing azobenzene was closed.
Optionally, a nano robot for precisely treating sewage is designed at the tail of the bionic body 1, as shown in fig. 4 and 5.
Specifically, the tail part of the bionic body 1 is filled with fluorocarbon emulsion fuel, and the tail part of the bionic body is also connected with an air injection structure; under the action of ultrasonic wave, the fluorocarbon emulsion fuel is vaporized and sprayed out from the air spraying structure, so that the nano robot is pushed to move at high speed.
In this embodiment, the air injection structure includes a plurality of tail pipes 6, and the tail pipes 6 are embedded with magnetic layers, and the swing direction of the tail pipes 6 is controlled by a magnetic field, so as to control the advancing direction of the nano robot.
Further, the tail tube 6 has a DNA spiral shape.
It should be noted that the bionic body 1 with the above volume is in a bionic fish shape.
The content of substances in the solution and the reaction conditions can be quantitatively monitored through the relationship between the reaction conditions and the movement speed; and when the movement speed is reduced, the sewage treatment device has long retention time at a polluted place, can repeatedly treat the sewage, and realizes the integration of monitoring and treatment.
For example, when toxic substances such as heavy metals, pesticides, etc. are present, the catalytic reaction degree of hydrogen peroxide is reduced, so that the movement speed is slow, and the distribution of the toxic substances in the water body is reflected.
The above embodiments only represent preferred embodiments, and the description is specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
