DNA and DNA nanoassemblies such as DNA origamis have large potential in biosensing, drug delivery, nanoelectronic circuits, and biological computing requiring suitable methods for migration and precise positioning. Insulator-based dielectrophoresis (iDEP) provides an efficient and matrix-free approach for manipulation of micro-and nanometer-sized objects. In order to exploit iDEP for naturally formed DNA and DNA nanoassemblies, a detailed understanding of the underlying polarization and dielectrophoretic migration is essential. The shape and the counterion distribution are considered two essential factors in the polarization mechanism. Here, the dielectrophoretic behavior of 6-helix bundle (6HxB) and triangle DNA origamis with identical sequences but substantial topological …
