729Ags-APMSNs126.91.5nmDLSPt nanodots with sizes of 2–3 nm formed a nanoisland shell on Au NRs from the transmission electron microscopy (TEM) image (Figure 2B). The average thickness of the mesoporous SiO2 layer surrounding the Au@Pt NR was around 25 nm (Figure 2C). The DLS results revealed that the effective diameter of Au NRs, Au@Pt NRs, and APMSNs with CTAB template were 17.1 ± 0.6, 46.0 ± 0.5, and 100.6 ± 0.7 nm, respectively. Table 1 further showed that the effective diameter of the APMSNs increased evidently from 92.1 to 126.9 nm after antigen conjugation process.
