The movement of magnetic particles when they pass through a magnetic field is called magnetic phosphorus. Until now, people still don’t know the factors that affect these particles and their motion. Now, researchers from the University of Illinois at Chicago have described several basic processes related to the movement of fluids through fluids because they are pulled by magnetic fields.

Their findings were published in the National Proceedings of the Academy of Sciences.

There are many applications for understanding the movement of magnetic particles when they pass through a magnetic field, including drug delivery, biosensors, molecular imaging, and catalysis. For example, magnetic nanoparticles containing drugs can be delivered to discrete points in the body after they are injected into blood or cerebrospinal fluid using a magnet. This process is currently used in some forms of chemotherapy to treat cancer.

&34; We need to learn more about how magnetic particles move so that we can better predict how fast they move, how many people will reach their goals, and when and what factors affect their behavior. Because they move through various fluids, &34;Meenesh Singh said they are made up of an assistant professor of chemical engineering in the School of Engineering and the corresponding author of the paper.

Meenesh and his colleagues found that four main factors affect the movement of magnetic particles:the difference between the magnetic properties of the particles and the solution in which they move, the gradient of the magnetic field, and the magnetic interaction between the particles. Or how much they stick together, and how the charge interacts with the particles and the magnetic field.

Andreas Linninger, a professor of bioengineering in the School of Engineering and the first author of the paper, said:”We can use this new knowledge to increase magnetic nanoparticles in the central nervous system. The specificity of the required target tissue in the system.

Based on these findings, the researchers created a mathematical formula that includes all these factors. They filled the model with real data and were able to accurately predict the speed and position of particles in the real system.

&34;By using our model, doctors and researchers will be able to better design magnetic nanoparticles to deliver drugs or other molecules, and perform these measurements more accurately,” Meenesh said. The model can also predict the motion of electromagnetic particles in various applications, including the deflection of charged particles in the Earth’s magnetosphere.
