Magnetic Nanorings are a form of magnetic nanoparticles, typically made of iron oxide in the shape of a ring. They have multiple applications in the medical field and computer engineering. In experimental trials, they provide a more localized form of cancer treatment by attacking individual cells instead of a general cancerous region of the body, as well as a clearer image of tumors by improving accuracy of cancer cell identification.[1][2] They also allow for a more efficient and smaller, MRAM (memory storage unit in a computer), which helps reduce the size of the technology houses it.[3] Magnetic nanorings can be produced in various compositions, shapes, and sizes by using hematite nanorings as the base structure.[4]
