摘要：
The present invention provides a fluorescent silica-based nanoparticle that allows for precise detection, characterization, monitoring and treatment of a disease such as cancer. The nanoparticle has a range of diameters, has a fluorescent compound positioned within the nanoparticle, and has greater brightness and fluorescent quantum yield than the free fluorescent compound, exhibits high biostability and biocompatibility, may be coated with an organic polymer, such as poly( ethylene glycol) (PEG). The small size of the nanoparticle, the silica base and the organic polymer coating minimizes the toxicity of the nanoparticle when admimstered in vivo. The nanoparticle may further be conjugated to a ligand. A therapeutic agent may be attached to the nanoparticle. Further, magnetic resonance imaging (MRI), radionuclides/radiometals or paramagnetic ions may be conjugated to the nanoparticle.
