Administration Route
Output Type Uptake/penetration (FACS time-course; confocal penetration imaging)
Output Value Time-dependent uptake; highest at 48 h; confocal shows deep penetration at 24 h
Output Units
Output Notes 3D spheroids showed increasing uptake from 3→48 h post-transfection; confocal imaging confirmed penetration through internal layers (DAPI nuclei; Cy3 signal).
