    • Nanoparticle compositions and methods are disclosed for the sustained release of small molecules, such as pharmaceutical compounds in vivo, for example ligand-lytic peptide conjugates. The construction of the nanoparticles helps to prevent self-aggregation of the molecules, and the consequent loss of effectiveness. The system employs layer-by-layer self-assembly of biocompatible polyelectrolyte layers, and layers of charged small molecules such as drug molecules, to form a multilayer nanoparticle in which the drug or other small molecule itself acts as one of the alternating charged layers in the multilayer assembly. The small molecules can then be released over time in a sustained manner. The LbL nano-assemblies can specifically target cancers, metastases, or other diseased tissues, while minimizing side effects.
    • 公开了纳米颗粒组合物和方法用于持续释放小分子,例如体内的药物化合物,例如配体 - 溶解肽缀合物。 纳米颗粒的构建有助于防止分子的自聚集,从而导致有效性的丧失。 该系统采用生物相容性聚电解质层和电荷小分子层(例如药物分子)的逐层自组装形成多层纳米颗粒,其中药物或其它小分子本身作为交替充电层之一 多层组件。 然后可以持续的方式随时间释放小分子。 LbL纳米组件可以特异性靶向癌症,转移瘤或其他患病组织,同时尽量减少副作用。
