Targeted cancer nanotherapy

Different nanometer-sized particles, which have optical, electronic, and structural properties that are not available from either individual molecules or bulk solids, are developed for Cancer nanotherapy. When linked with tumor-targeting moieties, such as tumor-specific ligands or monoclonal antibodies, these nanoparticles can be used to target cancer-specific receptors, tumor antigens and tumor vasculatures with high affinity and precision. Nanoscale devices can interact with biomolecules on cell surface and within the cells in a noninvasive manner, leaving the behavior and biochemical properties of those molecules intact. Nanoparticles have more surface areas and functional groups that can be linked to multiple optical, radioisotopic diagnostics.
