735	Au@Pt				TEM	The average length and width of the AuNRs were calculated to be 43.3 4.9 nm and 11.2 2.3 nm respectively (Fig. S1a and b, ESI†). The Pt nanodots were wrapped on the surface of the AuNRs homogeneously and formed a rough shell, as observed from Fig. 1b and c and Fig. S2b–d (ESI†). The average length and width were 57.9 4.9 nm and 14.5 2.6 nm respectively (Fig. S1c and d, ESI†). The HR-TEM image of Au@Pt nanorods (Fig. 1d) showed clear lattice distances of 0.224 nm and 0.231 nm, which can be assigned to the (111) planes of crystalline Pt and Au.
