Abstract:<div>Tracking the movement of fluorescent single-molecule (SM) tracers has provided several new insights on the local structure and dynamics in complex environments such as soft materials and biological systems. However, SM tracking (SMT) remains unreliable at molecular length scales, as the localization-error (LE) of SM trajectories (~30-50 nm) is considerably larger than size of molecular tracers (~1-3 nm). Thus, instances of tracer (im)mobility in heterogeneous media, which provide indicator for under… Show more
