Figure 3.

CLSM observations of the cellular uptake of the β-MENDs. The LPs were labeled with an NBD-DOPE, a fluorescent green dye. The cells were observed by CLSM after being incubated with the β-MEND (RES) (a) and the empty β-MEND (b), and the mitochondria were stained with Mito Tracker Deep Red. The non-treated cells were also observed (c). The colocalization of β-MENDs with mitochondria are indicated as yellow clusters. The panels below show higher magnification images framed by blue lines. Scale bars = 20 μm.
