document: MG unchanged and showed uniform size distribution when compared with the wild-type Qβ VLPs (WT-Qβ) using transmission electron microscopy (TEM) (Figure 1b); the diameter (Z-average) of Qβ@b-3WJsiSCR MG was slightly increased to 30.6 ± 0.4 nm from 30.4 ± 0.2 nm (WT-Qβ) measured by dynamic light scattering (DLS), as shown in Figure S3.
