Fig. 5From: Self-Assembled Superparamagnetic Iron Oxide Nanoclusters for Universal Cell Labeling and MRIEffect of the SPIO nanoclusters on LDH release. The SPIO nanoclusters (2.5, 5, 10, and 20 μg/ml) label NIH3T3, Raw264.7, and HepG2 cells for 24 h, which do not disrupt cell membrane as detected using LDH assayBack to article page
