Fig. 2From: Effective capture of circulating tumor cells from an S180-bearing mouse model using electrically charged magnetic nanoparticlesIllustration of the procedures for cancer cell capture. Cancer cells in suspension were mixed with NP+ and NP−, followed by 10 min of incubation. The “magnetized” cancer cells were pulled onto the wall of the vial using a magnet. After removal of the remaining solution, the cells were captured with NPs, washed and countedBack to article page
