Interaction between QDs-RBVs and actins. a Fluorescence images of QDs-RBVs, phalloidin-FITC labeled actins and their merge (arrows) in Sf9 cells. Typical velocity vs time plots (b) and MSD vs time plots (c) of the QDs-RBVs in Sf9 cells with (blue) and without (red) cytochalasin D treatment. The red curve and blue line in c is the fit to \({\text{MSD}} = 4D\tau + (V\tau )^{ 2} + {\text{constant}}\) and \({\text{MSD}} = 4D\tau^{\alpha } + {\text{constant}}\), respectively. d Histograms for the yields of baculoviruses propagated in untreated, nocodazole-treated and cytochalasin D-treated Sf9 cells
