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.
本发明通常涉及聚合物和大分子,特别是在像纳米颗粒这样的颗粒中有用的聚合物。本发明的一个方面涉及开发具有所需性质的纳米颗粒的方法。在一组实施例中,该方法包括产生具有高度控制的性质的纳米颗粒库,这些库可以通过混合不同比例的两种或更多种大分子来形成。其中一种或多种大分子可以是一个分子与
生物相容聚合物的共轭物。在某些情况下,纳米颗粒可能含有药物。本发明的其他方面涉及使用纳米颗粒库的方法。
