20100144845 | OLIGONUCLEOTIDE SYSTEMS FOR TARGETED INTRACELLULAR DELIVERY - The present invention provides methods for deriving oligonucleotides for specific internal delivery to one or more target cell types (e.g., cancer cells). The method generally includes selecting at least once with a target cell type to provide a plurality of internalizing oligonucleotides for the target cell type, and in some embodiments, counter-selecting at least once with a non-target cell type to provide a plurality of oligonucleotides that do not bind to features present in the non-target cell type. Therapeutic and diagnostic compositions including the oligonucleotides, and methods of treatment are also provided. | 06-10-2010 |

20090074828 | POLY(AMINO ACID) TARGETING MOIETIES - The present invention generally relates to polymers and macromolecules, in particular, to polymers useful in particles such as nanoparticles. One aspect of the invention is directed to a method of developing nanoparticles with desired properties. In one set of embodiments, the method includes producing libraries of nanoparticles having highly controlled properties, which can be formed by mixing together two or more macromolecules in different ratios. One or more of the macromolecules may be a polymeric conjugate of a moiety to a biocompatible polymer. In some cases, the nanoparticle may contain a drug. Other aspects of the invention are directed to methods using nanoparticle libraries. | 03-19-2009 |
