    • Upon using significantly longer deposition times to metallize DNA (typically 4 days), a large proportion of the surface is covered with precipitates, which enables their characterization by XPS. These precipitates appear to have exactly the same composition as the Pd(II)-NWs.

    • As an example, the parasitic metallization coverage increases from 0.1 to 0.9% of the surface when the deposition time is varied from 20 to 42h at 35°C.

    • The interpretation of the broadening and shifting of these lines with respect to pure crystallized PdO is not straightforward. Firstly, the presence of the PdCl4 salt can be ruled out since no signature of the Cl 2p line has been observed (this peak is indeed observed if the starting solution is not aged for 12 days to complete the hydrolysis of the salt, One possible explanation for the broadened and shifted peaks is the formation of a necklace-like structure (beyond the resolution of our microscopes) of ultra-small precipitates as described by a) J. C. Bertolini, P. Delichere, B. C. Khanra, J. Massardier, C. Noupa, B. Tardy, Catal. Lett. 1990, 6, 215;
