Comparison of cytotoxic effects of magnetic beads on human breast cancer cell line MCF-7, ovarian cancer cell line SKOV3, and normal human lung fibroblasts MRC-5 and IMR-90. Panels a–d are the phase-contrast microscopic images showing cell growth and colony morphology of MCF-7 (a), SKOV3 (b), MRC-5 (c), and IMR-90 (d) cell lines after magnetic beads treatments. Panels e–h show the cell viabilities of the used nanostructures in MCF-7, SKOV3, MRC-5, and IMR-90, respectively
