Using Nanotechnology, Researchers Extract A Single Strand of DNA

A team of scientists and engineers from the University of Wisconsin-Madison (and from the Delft University of Technology) has discovered a way to look at a single strand of DNA—by positioning the molecule in nanoscale “slits.” Currently, in order to study DNA molecule, scientists must look at collections of molecules floating in a solution, and extracting a single molecule makes it a time-consuming process. The research team reports that their method of positioning single DNA molecules in nanoscale troughs is both inexpensive and quick. The research was supported by federal grants from the NSF and the NIH.
