Fig. 4From: Methylene blue associated with maghemite nanoparticles has antitumor activity in breast and ovarian carcinoma cell linesAlteration of morphology of cancer cell lines after exposure to MAGCIT–MB treatment. Scanning electron micrograph (SEM). NT (cells without treatment) and cells treated with MAGCIT–MB after 48 h (0.78 µg mL−1 of MB). Arrows indicate cell adhesion points and arrowheads, changes in the cell surface. Scale bar = 10 µmBack to article page
