Compositions comprising a polymeric micellar nanoparticle composition comprising a block or graft copolymer comprising at least one polycationic polymer and at least one polyethylene glycol (PEG) polymer having an average molecular weight less than 1 kDa, and at least one nucleic acid, wherein the graft or block copolymer and at least one nucleic acid are complexed and condensed into a shaped micellar nanoparticle that is stable in biological media are disclosed. The presently disclosed subject matter also provides a method for preparing the presently disclosed polymeric micellar nanoparticle compositions, a method for targeting at least one metastatic cancer cell in a subject, and a method for treating a disease or condition using the presently disclosed polymeric micellar nanoparticle compositions.

Virus particle multimers and methods of making and using such virus particle multimer are described. Virus particle multimers are constructed by preparing a plurality of asymmetrically functionalized virus particles bearing one or more functional groups and contacting the asymmetrically functionalized virus particles with a first linker molecule that reacts with the functional groups to form a virus particle multimer that includes a plurality of asymmetrically functionalized virus particles connected by the linker molecule. The asymmetrically functionalized virus particles are typically prepared by attaching the virus particles to a support surface to allow asymmetrical functionalization to be introduced.
