Abstract

Antibodies play an essential role in various applications. However, antibodies exhibit considerable challenges in applications that require tunable binding capabilities and exposure to nonphysiological conditions such as chemical conjugation. This study is aimed to develop a novel antibody-like nanostructure with special features. The key components of the nanostructure are two DNA aptamers and a dendrimer. The aptamers are used to mimic the antigen-binding sites of an antibody; the dendrimer is used to provide a defined conjugation site for carrying molecules of interest. The results showed that the bivalent nanostructure exhibited a high binding affinity and specificity. Moreover, a temperature shift from 0 to 37 °C would trigger its rapid dissociation from the bound target cells, which is not possible in antibody-antigen complexes. Thus, an antibody-like nanostructure was successfully developed with novel features that natural antibodies do not possess.
