Macrophage binding and uptake of NBD-labeled nanoparticles in vitro. THP-1 derived macrophages were treated with NBD-labeled Vnano and L-Vnano at either 4°C (A) or 37°C (B); the macrophages were treated with NBD-labeled Vnano or L-Vnano in combination with oxLDL at 37°C (C); Macrophages were treated with NBD-labeled Enano and L-Enano at 37°C (D). Images are representatives of three independent experiments.
