Abstract: The present invention relates to a nanostructure comprising: a) a nucleic acid scaffold; and b) at least two peptide moieties, wherein the at least two peptide moieties specifically bind to a molecule expressed on the surface of a virus and are attached to the nucleic acid scaffold, wherein the structure of the nucleic acid scaffold is selected from the group of: i) a linear nucleic acid scaffold, wherein the at least two peptide moieties are each attached at or near different ends of the nucleic acid scaffold; and ii) a branched nucleic acid scaffold, wherein the at least two peptide moieties are each attached to a different branch of the scaffold. The invention furthermore relates to the nanostructure of the invention for use as a medicament, and more specifically for use in the treatment of viral infections. The invention also relates to the nanostructure of the invention for the use in diagnostic purposes and in methods of detecting whether a virus is present in a sample.
