Abstract: The present invention provides structures formed from crosslinked polynucleotides, where a subset of the polynucleotides binds to a target under physiological conditions, where the signal group detectably changes upon binding.

Abstract: Articles, compositions, kits, and methods relating to nanostructures, including synthetic nanostructures, are provided. Certain embodiments described herein include structures having a core-shell type arrangement; for instance, a nanostructure core may be surrounded by a shell including a material, such as a lipid bilayer, and may include other components such as oligonucleotides. In some embodiments, the structures, when introduced into a subject, can be used to deliver nucleic acids and/or can regulate gene expression. Accordingly, the structures described herein may be used to diagnose, prevent, treat or manage certain diseases or bodily conditions. In some cases, the structures are both a therapeutic agent and a diagnostic agent.

Abstract: Articles, compositions, kits and methods relating to nanostructures, including those that can sequester molecules such as cholesterol, are provided. Certain embodiments described herein include structures having a core-shell type arrangement; for instance, a nanoparticle core may be surrounded by a shell including a material, such as a lipid bilayer, that can interact with cholesterol and/or other lipids, and an apolipoprotein may be bound to at least the outer surface of the shell. In some embodiments, the structures, when introduced to a subject, can sequester cholesterol and/or other lipids and remove them from circulation. Accordingly, the structures described herein may be used to diagnose, prevent, treat or manage certain diseases or bodily conditions, especially those associated with abnormal lipid levels.

Abstract: Materials and methods for regulating gene expression using nanoparticles functionalized with antisense oligonucleotides are provided.

Abstract: The present invention relates to screening methods, compositions, and kits for detecting for the presence or absence of one or more target analytes, e.g. biomolecules, in a sample. In particular, the present invention relates to a method that utilizes reporter oligonucleotides as biochemical barcodes for detecting multiple protein structures or other target analytes in a solution.
