Abstract: Methods for leveraging the charged nature of DNA to promote DNA extension and manipulate its orientation are provided. The methods include attaching highly charged molecules to a free end of a DNA molecule to transform the DNA molecule into a pseudo dipole. Upon applying an external electric field, the charge separation may cause the DNA to extend and/or to align with the electric field lines. This approach offers a practical means to achieve a controlled, unfolded state of DNA with a predetermined orientation.
