Live imaging of moving HT-1080 cell that actively uptakes MNPs from the glass surface. Time scale from the beginning of the recording is indicated in the upper-left corner of each image (left column). Left column (a, c, e, g) represents successive photos of the cell, right column (b, d, f, h) represents a sketch of the movie with free MNPs shown in black and internalized MNPs in red (see also Additional file 1: Movie 1)
