摘要: The present invention generally relates to nanoparticles with an amphiphilic component. 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.

摘要: A method for encapsulating nucleic acids, particularly siRNAs, shRNAs, microRNAs, gene therapy plasmids, and other oligonucleotides in biodegradable polymers is disclosed, whereby the nucleic acids are formulated into reverse micelles composed of non-toxic and/or naturally-occurring lipids prior to nanoparticle formation by nanoprecipitation. This method can be coupled to other techniques that improve intracellular drug targeting, ultimately enhancing intracellular delivery of the aforementioned nucleic acids.
