The authors have electrospun fluorescently labeled DNA molecules into nanofibers with diameters of approximately 27 nm. They were able to image the nanofibers via fluorescence microscopy, scanning electron microscopy, and atomic force microscopy. Fibers were deposited over prepatterned features such as electrodes and trenches, allowing future measurement and manipulation of the DNA nanofibers. As an example of such a measurement, they have used an atomic force microscope to measure the Young's modulus of a single DNA nanofiber.
