Trajectories of trapped particles as a function of time (time step, 33 ms) obtained by tracking the centroids of the particles. The monitored particles were marked by colored arrows in fluorescence micrographs. (a) Plasmonic optical trapping on a ARNSL surface in 1.0 s, (b) MFBS-assisted 2D-trapping (corresponding to Fig. 1) in 2.7 s and (c) 1D-trapping (corresponding to Fig. 3) in 10 s. Insets in panel (b,c) show the expanded views. From the figures, it is obvious that MFBS-assisted trapping can perform a very tight trapping. A particle is almost immobilized in Fig. 5(c).
