Intracellular observation of nanocarriers modified with a mitochondrial targeting signal peptide.

This study focused on the intracellular observation of nanocarriers modified with a mitochondrial targeting signal peptide (MTS). The nanocarriers showed an efficient cellular uptake, and the MTS had a positive effect on their mitochondrial targeting. This is the first report of an intracellular observation of nanocarriers modified with MTS.
