Progress of magnetic iron oxide nanoparticles in targeted diagnosis and treatment of pancreatic cancer

Abstract

Pancreatic cancer has a very poor prognosis. Early diagnosis and treatment are especially critical for improving its prognosis. Nanotechnology has been widely used in the diagnosis and treatment of pancreatic cancer. Relying on the unique physicochemical properties of nanoparticles and their rich surface modifications, effective enrichment of tumor sites can be achieved. Magnetic iron oxide nanoparticles (MIONPs) is one of the commonly used nanomaterials in the diagnosis and treatment of pancreatic cancer, and has good biocompatibility. Through special surface modification, it can be used in targeted diagnosis and treatment of pancreatic cancer. MIONPs can be used as a contrast agent for MRI, and by modifying the surface, they also can be used in targeted imaging of pancreatic cancer. And they can also be modified as a drug delivery system to achieve targeted delivery of drugs and improve therapeutic effects. However, the application of MIONPs in pancreatic cancer diagnosis and treatment still faces some challenges, such as nanotoxicity and cost issues. With the development of technology, MIONPs are expected to play an important role in the personalized diagnosis and treatment of pancreatic cancer.
