(a) A temporal profile of fluorescence intensity during 1D-trapping of polystyrene nanospheres (d = 500 nm) by laser irradiation to a MFBS substrate. This corresponds to the case of Fig. 3. 808 nm light Irradiation period consists of the area (I) and area (II). (b) A representative fluorescence spectrum measured at the time region (I) together with that measured at the region (II).
