Transmission electron microscopy of higher generation Gd-dendrimers. Annular dark-field scanning transmission electron microscopy (ADF STEM) images of unstained Gd-G5, Gd-G6, Gd-G7, and Gd-G8 dendrimers adsorbed onto an ultrathin carbon support film. The diameters of one hundred Gd-G7 and Gd-G8 dendrimers were measured. Scale bar = 20 nm.
