WebHerein, mitochondria-targeting Pt nanoclusters were synthesized using cytochrome c aptamer (CytcApt) as template. The obtained CytcApt-PtNCs can produce ⋅ OH by H 2 O 2 under the acidic conditions. Moreover, CytcApt-PtNCs could kill 4T1 tumor cells in a pH-dependent manner, but had no side effect on normal 293T cells.
