Experimental Research On Molecular Communication Based On Magnetic Nanoparticles

With the great progress in fields such as nanotechnology and bioengineering,nanoscale devices have begun to enter people’s lives,and health monitoring using nanorobots with medical sensors is a potential application for nanoscale devices.However,reliable communication between these nanoscale devices is a difficult problem.Inspired by nature,people began to use some biochemical particles as carriers of information to provide nanoscale devices with a communication method called Molecular Communication.Molecular communication is biocompatible and requires very little energy to generate and propagate,making it one of the most promising ways to build nanonetworks.The current research on molecular communication mainly focuses on theoretical research,and mainly studies the molecular communication at the microscopic scale,such as targeted drug delivery,nanorobots carry therapeutic drugs to a specific location in the human body to release drugs to improve treatment efficiency,and reduce the impact on other body parts.The research on molecular communication requires relevant experimental platforms to verify some theories.At present,there are relatively few researches on molecular communication experimental platforms,and even less research on molecular communication experimental platforms based on magnetic nanoparticles.Therefore,it is necessary to design molecular communication experimental platforms for experiments,so as to get rid of pure theoretical research.This paper mainly designs and implements a molecular communication experimental platform based on magnetic nanoparticles to study the influence of different modulation methods and different external factors on molecular communication.The main work of this paper is as follows:(1)Introduce the current research background and research status of molecular communication.Expound the theoretical basis of molecular communication,molecular diffusion model and the analysis of magnetic nanoparticles under the action of magnetic field.Explain that molecular communication has a revolutionary role in the research of constructing nano-networks in the human domain,and analyse the advantages and disadvantages of molecular communication compared with traditional communication.In view of the current situation that molecular communication mainly focuses on theoretical research,this paper explains the importance of designing and implementing a comprehensive experimental platform for molecular communication.(2)Designed and implement a comprehensive experimental platform for molecular communication based on magnetic nanoparticles.Magnetic nanoparticles are used as messenger molecules to modulate the information carried by the magnetic nanoparticles through three signal modulation methods: molecular concentration modulation,molecular release frequency modulation and molecular release time modulation.The concentration of messenger molecules in the signal receiving area is detected non-contact by Hall sensor.The basic molecular communication process is successfully realized in the molecular communication experimental platform.(3)Research the effects of temperature,flow rate and p H value on molecular communication.In this paper,a constant temperature closed box is designed,and non-contact temperature control and non-contact flow rate measurement are carried out in it.An ultrasonic processor device was also designed,and the magnetic nanoparticles could be fully embedded on the surface of Ganoderma Lucidum Spores by ultrasonic vibration,and the experimental solution was subjected to acid-base titration in the ultrasonic processor,and the p H value of the solution was controlled by a p H sensor.(4)The communication feasibility experiment was carried out on the molecular communication platform designed and implemented in this paper.Moreover,the molecular communication under different signal modulation methods and the influence of temperature,flow rate and p H value on molecular communication were researched.
