    摘要: The invention described herein relates to sterically stabilized colloidal constructs comprising preformed colloidal particles encapsulated within a polymeric shell. The constructs, which are controllably sized, are nanoparticles comprising hydrophobic elements, electrostatically charged particles with hydrophobic surfaces, hydrophobic inorganic nanostructures, and amphiphilic copolymers with hydrophobic domains and hydrophilic domains. The constructs are made by a process that allows for the simultaneous encapsulation of a preformed colloidal agent as well as a dissolved hydrophobic active within the core of the polymeric nanoparticle. Among the actives incorporated in various embodiments are organic fluorescent dyes, metal nanostructures and superparamagnetic materials for use in combined fluorescence, optical and magnetic resonance imaging applications, and hydrophobic drugs for therapeutic applications.

    摘要: The instant invention provides for novel lipid nanoparticle (LNP) formulations, containing cationic lipids, for use as vaccine adjuvants and/or as antigen delivery systems. It is an object of the instant invention to provide LNP formulations that demonstrate enhancements in humoral and cellular immunogenicity of vaccine antigens, particularly subunit vaccine antigens, when utilized alone or in combination with immunostimulatory agents (e.g. small molecule or oligonucleotide TLR agonists). The instant invention further identifies physical and chemical properties of the LNP formulations that can be manipulated to enhance antigen efficiency and adjuvant tolerability in vivo.
