Embodiment Construction

[0019] In order to facilitate those skilled in the art to understand the technical content of the present invention, the content of the present invention will be further explained below in conjunction with the accompanying drawings.

[0020] The technical solution of the present invention is: the target continuously releases a certain attractant, and the artificial nanomachine calculates the concentration difference through the concentration of the attractant detected by the sensor to judge the concentration gradient, and then guides the nanomachine to move towards the direction of high concentration, and finally Quickly reach the target area, so as to achieve the effect of directional communication. The target area here refers to an area range that is relatively close to the target object, usually a circular area with the target object as the center, and the specific area size depends on the actual application requirements. Usually the radius of the area is 0.1-5cm, the small...

Abstract

The invention discloses a target orientation method in mobile molecule communication on the basis of concentration gradient. Under a mobile molecule communication scene, a target object continuously releases some baits, and a nanometer machine collects the concentration of the baits in a medium through a concentration sensor in real time and calculates the concentration difference; secondly, according to the concentration difference, the concentration gradient of the medium is judged, and then the nanometer machine moves to the place where the concentration is high and reaches a target area atlast. By introducing the chemotactic effect principle of bacteria in biology into mobile molecule communication, the delay problem caused by random dispersion in the molecule communication is solved,time for the nanometer machine to move to the target area is effectively shortened, and the communication efficiency is improved. The method is widely applicable to scenes with baits during mobile molecule communication based on a dispersion mode and can be widely applied to oriented drug delivery, targeted treatment and the like in medical treatment.

Description

technical field [0001] The invention belongs to the field of mobile molecular communication, and in particular relates to a fast guiding algorithm for a nanomachine to move toward a target according to the concentration of attractants in the surrounding medium during the mobile molecular communication. Background technique [0002] Molecular communication is an emerging interdisciplinary technology in recent years, involving biology, medicine, communication and other fields. Molecular communication uses nanoscale molecules as information carriers to complete intercellular information transfer in organisms. The most common communication method based on diffusion is the most common one in molecular communication, that is, molecules reach their destination through free diffusion and complete the communication process. Artificial nanomachines can be regarded as artificial nanoscale biological cells, which are an important means of molecular communication. Mobile molecular comm...
