Gd³⁺-Asparagine-Anionic Linear Globular Dendrimer Second-Generation G2 Complexes: Novel Nanobiohybrid Theranostics

Figure 12

Size and charge measurement for Gd³⁺-dendrimer G2-asparagine. It is well previously [20, 21] shown that dendrimer alone has -1-2 mV charge and ~90 nm size. The data was also confirmed by AFM imaging results as depicted above: (a) Gd³⁺-asparagine-dendrimer G2, 2D image; (b) Gd³⁺-asparagine-dendrimer G2, 3D image; (c) dendrimer G2, 2D image; (d) dendrimer G2, 3D image.
