    • In all cases, the samples were excited at 300 nm and the time before measuring was set to 5 h, as conjugation was proven to be complete. This wavelength was selected to guarantee that mostly the quantum dots were excited. All emission spectra have been adjusted to their absorption at 300 or 450 nm

    • Transient absorption measurements with cytochrome c in either oxidation state reveal mainly features that are best described as the mirror image to the ground state absorptions in the visible-see Figures S8 and SlO, Supporting Information, These transients are, however, very shortlived and decay with lifetimes of 8.1 and 6.3 ps for Fe(II) and Fe(III, respectively, quantitatively back to the ground state. Please find the corresponding time-absorption profiles in Figures S9 and S11 Supporting Information
