Visualizing Structure of Bio-Functional Magnetic Nano-Particles with Analytical Electron Microscopy

摘要

The analytical electron microscopic images of bio-functional magnetic particles demonstrate the unique structures and how they function as designed in bio-applications. These results verify a simple and cost-effective approach to synthesize the surface modified magnetic particles with the capability of controlling particle size, crystalline structure, and uniformity. In addition, the feasibility of magnetic particles for DNA binding has also been demonstrated by these direct imaging results.
