NANOPARTICLES AND COATED NANOPARTICLES

摘要

The present invention relates to materials and methods comprising nanoparticles, such as semiconductor nanoparticles and magnetic semiconductor nanoparticles. Nanoparticles of the invention may exhibit useful properties which can be tailored with a high degree of control using various methods of the invention. In some embodiments, the nanoparticles may formed to exhibit a certain property or combination of properties, such as optical and magnetic properties. The present invention also provides coatings (e.g., silica coatings) and related methods which may enhance various properties of the nanoparticles. Nanoparticles described herein may 0 be useful in applications such as labeling of biological species, drug targeting, magnetic resonance imagine (MRI), among other applications.
