Administration Route
Output Type Fluorescence microscopy mRNA imaging (TO emission); compare +dox vs -dox
Output Value Delivered; diffuse cytosolic fluorescence stronger in +dox than -dox, but massive fluorescent spots in both conditions.
Output Units
Output Notes Indicates uptake and some target recognition, but strong spot-like artefacts/high background from aggregates or compartmentalization.
Toxicity Notes
Curation Notes
