Abstract
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.
