Utility Of Multivalent Aptamers To Develop Nanoscale Dna Devices Against Surface Receptors

DNA nanotechnology is undergoing rapid progress in the assembly of functional devices with biological relevance. In particular, currently, the research attention is more focused on the application of nanodevices at the interface of chemistry and biology, on the cell membrane where protein receptors communicate with the extracellular environment. This review explores the use of multivalent nucleic acid ligands termed aptamers in the design of DNA-based nanodevices to probe cellular interactions followed by a perspective on the untapped utility of XNA and UBP nanotechnology in designing functional nanomaterials with broader structural space.
