Tracking of three individual Ag Plasmon Rulers, PR1-3, on isolated plasma membranes through PRCPM. The Ag dimers were assembled through a DNA-programmed self-assembly strategy and were then monitored on plasma membranes of lysed HeLa cells. Left column: Plasmon Ruler trajectory. Right column: intensity ratios, R (red), degree of light polarization, P (black), and approximate interparticle separation, S (blue), as function of time.
