    摘要: A method for the production of biodegradable nanoparticles with an average particle size of less than 400 nm. In a first step, a macromonomer is prepared in a ring opening polymerization process between a hydrophilic acrylate compound (A) as an initiator and hydrophobic cyclic monomers (B), wherein the macromonomer comprises at least two repetitive units based on the cyclic monomer. In a second step, this macromonomer or a mixture of macromonomers and/or commercial biocompatible monomers is polymerized, e.g. in a starved, miniemulsion or emulsion radical polymerization in water in the presence of a surfactant to the nanoparticle without necessitating additional subsequent steps for the actual production of the nanoparticles. The correspondingly made nanoparticles and uses thereof also are disclosed.

    摘要: The invention provides novel methods, materials and systems that can be used to generate viral vectors having altered tissue and cell targeting abilities. In illustrative embodiments of the invention, the specificity of lentiviral vectors was modulated by a thin polymer shell that synthesized and coupled to the viral envelope in situ. The polymer shell can confers such vectors with new targeting ability via agents such as cyclic RGD (cRGD) peptides that are coupled to the polymer shell. These polymer encapsulated viral vectors exhibit a number of highly desirable characteristics including a higher thermal stability, resistance to serum inactivation in vivo, and an ability to infect dividing and non-dividing cells with high efficiencies.
