Suitable applications include elaboration of composite materials and, in particular, of nano-composite materials, materials intended for photovoltaics, detection devices of the detector/sensor or biodetector/biosensor type, photocatalysis systems, targeted vectorization systems for compounds of therapeutic or diagnostic interest or further contrast agents for medical imaging.
Abstract:
A rod-shaped plant virus having an interior surface and an exterior surface, and at least one imaging agent that is linked to the interior and/or exterior surface is described. The rod-shaped viruses can be combined into larger spherical nanoparticles. A rod-shaped plant virus or spherical nanoparticles including an imaging agent can be used in a method of generating an image of a tissue region of a subject such as a tumor or atherosclerotic tissue by administering the virus particle to the subject and generating an image of the tissue region of the subject to which the virus particle has been distributed.

Abstract:
The present invention includes compositions, methods and pharmaceutical compositions formed by template-directed polymer molding by contacting a porous template with one or more layers of polymeric material coated on a release layer coated on a substrate, applying pressure to the porous template, the substrates or both and separating the porous template from the polymer material to form one or more polymer nonspherical nanostructures with one or more layers on the substrate. The template includes one or more nonspherical nanostructure features. The size and shape of the one or more single- or multi-layer polymeric nonspherical nanostructures are controlled by the one or more nonspherical nanostructure features and the polymer material optionally including one or more active agents with or without retardants, dyes, etc.
