Synthesis, Characterization, and In Vitro Drug Delivery Capabilities of (Zn, Al)-Based Layered Double Hydroxide Nanoparticles

Figure 7

(a) shows GaussView 03 generated 3D representation of the optimized geometry of VP by spin unrestricted B3YLP method using 6-31 basis set. In (b), the intercalated VP are proposed to be in double layer orientation with different hydration levels according to the interlayer spacing calculated from XRD pattern and the optimized geometry of the VP.
