Tuberculosis: pH-Responsive Isoniazid-Loaded Nanoparticles Markedly Improve Tuberculosis Treatment in Mice (Small 38/2015).

On page 5066, J. I. Zink, M. A. Horwitz, and co-workers use confocal microscopy to demonstrate the avid uptake of RITC-labeled mesoporous silica nanoparticles loaded with the anti-tuberculosis drug isoniazid (shown here in red) by human macrophages (nuclei stained blue with DAPI) infected with GFP-expressing Mycobacterium tuberculosis (shown here in green).
