Researchers have developed the world's first three-dimensional plasmon rulers, capable of measuring nanometer-scale spatial changes in macromolecular systems. These 3-D plasmon rulers could provide unprecedented details on such critical dynamic events in biology as the interaction of DNA with enzymes, the folding of proteins, the motion of peptides or the vibrations of cell membranes.
