Topic Area: 
Magnetic Iron Oxide Nanoparticles (MION) as a Drug Carrier

Magnetic iron oxide nanoparticles (MION) have been widely and intensively used as a MRI enhancer or studied as a drug delivery carrier candidate. Our study is dedicated to the double applications as a MRI enhancer and a drug delivery system of MION simultaneously.

As a drug delivery carrier of MION for the brain tumor treatment, usually, we have to conjugate some drug and targeting protein etc. on the surface. An external magnetic field is also needed to guide the magnetic particle to the targeting site such as tumor. In this case, the strong magnetic response force and thus higher saturation magnetization and larger size are wished. Here, we have to consider the particle half-life time in the circulation due to the macrophage clearance for the larger size and the difficulty of particle transfer through brain blood barrier. Once the particle reaches the targeting site, we wish it will not be washed out quickly due to the blood flow. On the other hand, as a MRI enhancer, the particle is small in size generally. Clearly, some factors and requirements are in conflict.

What kind of magnetic properties is suitable for both the applications?

What kinds of structures match both the applications?

The purpose of my project is to design and synthesize some kinds of structures of MION for the applications.

Brief Biography:

Dr.Yu, born in China, especially likes to go on a hike in mountain or forest areas, enjoying the natural landscape, listening to the birds' songs, and breathing the fresh air. He also likes to travel by train, chatting with natives to learn some local custom and culture. Besides doing experiments on polymer and magnetic particles, he likes to do some crafts, cook, and play sports. Spicy foods, with a little beer, are his favorite. His biggest wish is to view our planet from space.
