The non-specific uptake of these AuNRs by cells was also studied under dark-field microscopy. Our work demonstrates that the coating of AuNRs surfaces with PEG-SH or PEO–PPO–PEO

• , respectively. The morphology and particle size in aqueous solution were determined by transmission electron microscopy (TEM) and dynamic light scattering (DLS), with satisfactory agreement between both techniques. In general, these fullerene derivatives are shown to organize into spherical nano-scale

• report on the morphological characterization of four fullerene–androsterone conjugates in water. The morphology and particle size of the C60–androsterone hybrids in aqueous solution were determined by transmission electron microscopy (TEM) and dynamic light scattering (DLS). Results and Discussion The

• of the difference in hydrophilicity of the androsterone moieties in both diasteromeric pairs. The presence of a carbonyl group in Ia,b instead of a less polar group such as acetoxy in IIa,b, promoted the formation of smaller vesicles. Dynamic light scattering DLS measurements gave further information

• diameters of void PGMD NPs and IR820-PGMD NPs (see dynamic light scattering (DLS) measurements in Figure S1, Supporting Information File 1) are 90 ± 18.2 nm, and 108 ± 7.4 nm (mean ± SD) respectively. The shape and size of IR820-PGMD NPs were also confirmed with scanning electron microscopy (SEM) imaging
