Localization of magnetic nanoparticles at 1 week.

Abstract

<p>At 1 week after IVT injection, immunofluorescence was used to localize 50 nm particles (green in a) and 4 µm particles (red in b) as shown by white arrows. In both cases, retinas were counterstained with GFAP and DAPI (nuclei, blue). At 1 week, both sizes of magnetic particles were detectable in the ganglion cell layer (arrows). Scale bar, 50 µm.</p
