a
Morphologies determined by TEM are indicated as S (spheres) and C (cylinders).
b
Mean dimensions refer to sphere diameters or cylinder widths determined by TEM. Errors represent standard deviations of mean values of three separate nanoparticle preparations under the same conditions.
c
Effective hydrodynamic diameters determined by DLS using cumulent analysis. Errors represent standard deviations of mean values of three separate nanoparticle preparations under the same conditions.
