| Ludwig Maximilians University researchers have used DNA to build a ‘hand’ that can grasp and release single molecules. The DNA machine may, eventually, be able to construct materials and machines one molecule at a time. The hand uses DNA branch migration to switch between various structural arrangements. One configuration has an open sequence of bases that will bind to a specific protein. This means the hand can grab that protein. Another configuration doesn’t have the sequence and the protein is released. |
