Currently the treatment of diseases primarily depends on the delivery of medicines with the help of magnetic nanofragments in the human circulatory system. In this treatment, drug particles and magnetic nanoparticles are introduced into the bloodstream and shipped to the appropriate organs under magnetic intensity, which is normally applied locally and helps to promote the release of drugs. This approach is used in numerous medicinal processes, including as the healing of cancer, the targeted administration of drugs, the wound-healing process of wounds, reducing bleeding in the course of surgical treatment, and the magnetic attraction of blood. Therefore, the purpose of this paper is to conduct a theoretical analysis of blood flow of a Casson fluid that is carrying hematite (Fe2O3) and magnetite (Fe3O4), two different types of magnetic nanoparticles, across a planar surface. The MATLAB mathematical tool's built-in Bvp4c function was used to plot the results graphically. The fluid kinetic energy is absorbed by the magnetic field via the Lorentz force, which reduces any disruptions and prevents the flow from transitioning. Temperature fluctuations are dissipated by thermal radiation, increasing the amount of magnetic nanoparticles in the vicinity of the tumour tissue. The Casson parameter keeps the instabilities that cause the nanoparticles to precipitate in place and permits easy horizontal flow. The findings have a significant impact on medicine and potentially save costs and post-operative difficulties in patients by treating vascular and malignant diseases without necessity for surgery
