The Results Miltenyi nanoparticles are retained by T cells, after 72hr incubation Forward this video to a colleague What you’re about to see: Confocal, iso-surface and TEM images reveal Miltenyi nanoparticles internalizing in human CD3+ T cells.  Miltenyi nanoparticles accumulating in human CD3+ T cell vesicles.   What this means: After 72 hours (see new TEM's below), Miltenyi nanoparticles are not biodegraded.  In contrast, Dynabeads® are released and removed from the cells.
