Figure 2. Atomic force microscopy of curcumin-ND.
Samples were incubated on an atomically flat Muscovite mica surface in imaging buffer (PBS with 10 mM MgCl2) then lightly rinsed. Topographical images were obtained with silicon nitride cantilever probes with a spring constant of 0.05 N/m. (A) Empty ND. (B) Curcumin-ND. Scale at right represents a color-coded measurement of height (nm).
