Confocal images of the MH-S cells treated with the QD-encoded polyelectrolyte microcapsules coated with BSA. The upper row shows the images of the samples after 4 h of short-term incubation; the microcapsules are shown by white arrows (a–d). The lower row demonstrates the images of the samples after 24 h of long-term incubation; the microcapsules are shown by white arrows (e–h). The nuclei of the macrophages were counterstained with far-red DNA stain DRAQ5
