Delivery of a cell-membrane-impermeable diruthenium complex to live cancer cells by using the GNP–M1/MC2(EG12)3. (A) Chemical structure of the diruthenium(II) complex, BPY. (B) Confocal phase contrast (left), fluorescence (middle), and merged optical/fluorescence images (right) of HeLa cells after treatment with the BPY for 3 h at 37 °C. (C) Confocal phase contrast (left), fluorescence (middle), and merged optical/fluorescence (right) images of HeLa cells after incubation with GNP–M1/MC2(EG12)3–BPY for 3 h at 37 °C.
