(a) The diameters of some typical cells are summarized (solid lines). Dashed lines display the size distribution of the two types of circulating tumor cells (CTCs) (KATO III and MCF-7) clusters with two CTCs. (b) Illustrations of the co-cultivation process of the red fluorescent protein (Hela-RFP) cell with the magnetic nanoparticles (MNPs), and (c) the SEM image of the MNPs-labeled Hela-RFP. (d) SEM image of the surface attached of MNPs. (e) The green fluorescent protein (Hela-GFP) cells used to represent white blood cells (WBCs), and (f) the SEM image of the Hela-GFP cell morphology.
