abstract = {We demonstrate the long time trapping of single DNA molecules in liquids by feedback driven dynamic temperature fields. By spatially and temporally varying the temperature at a plasmonic nanostructure, thermophoretic drifts are induced that are used to trap single nano-objects. A feedback controlled switching of local temperature fields allows us to confine the motion of a single DNA molecule for minutes. The DNA conformation and conformation dynamics are analyzed in terms of a principle component analysis. Current results are in agreement with previous measurements in thermal equilibrium and suggest only a weak influence of the inhomogeneous temperature rise on the structure and dynamics in the trap.},
