The translation of proteins as effective intracellular drug candidates is limited by the challenge of cellular entry and their vulnerability to degradation. To advance their therapeutic potential, cell-impermeable proteins can be readily transformed into protein spherical nucleic acids (ProSNAs) or encapsulated into liposomal spherical nucleic acids (L-SNAs), structures defined by...
Over the past fifty years, techniques for synthesizing and manipulating matter on the 1-100 nanometer scale have led to the development of nanoparticle-based approaches to both disease diagnosis and treatment. The modification of nanoparticles with biological macromolecules such as proteins and nucleic acids has led to the development of highly...
Spherical Nucleic Acids (SNAs) are unique class of nanomaterial characterized by a dense nucleic acid shell conjugated to a nanoparticle core. This radial orientation of oligonucleotides and architecture distinguishes SNAs from the components from which they are comprised. Specifically, unique chemical and biological properties emerge that are not observed with...
Spherical Nucleic Acids (SNAs) are nanoparticle bioconjugates that have found use in a wide-range of diagnostic and therapeutic applications. These nanomaterials are composed from inorganic or organic core nanoparticle scaffolds that are functionalized with a dense surface layer of nucleic acids (typically DNA or RNA) that are oriented in a...
