Figure 2From: Effect of surface properties of silica nanoparticles on their cytotoxicity and cellular distribution in murine macrophages Localization of unmodified and modified nanosilica in RAW 264.7 cells. RAW 264.7 cells were treated for 3 h with 100 μg/ml of fluorescent (green-F)-labeled nSP70 (a, b), nSP70-N (c), and nSP70-C (d) (green). The nucleus was counterstained using DAPI (blue). The original magnification of these photographs was × 63 (a) and × 100 (c, d). (b) is a magnified image of a portion of photograph (a).Back to article page
