The use of single molecules to study local, nanoscale polymer dynamics is presented. Fluorescence lifetime fluctuations were used to extract the number of polymer segments (Ns) taking part in the rearranging volume around the probe molecule below the glass transition temperature. Ns was dependent on the temperature and it decreased with increasing… CONTINUE READING
