Dendrimers pertain both to the molecular chemistry world for their step by step controlled syntheses, and to the polymer world because of their repetitive structure made of monomers; thus they benefit from analytical techniques from both worlds. This review is a survey of the main analytical techniques used for the characterization of the chemical composition, the morphology, the shape, and the homogeneity of dendrimers. It includes NMR, IR, Raman, UV-Visible, fluorescence, circular dichroism, X-ray diffraction, mass spectrometry, SAXS, SANS, Laser Light Scattering, microscopy, SEC, EPR, electrochemistry, electrophoresis, intrinsic viscosity, DSC, and dielectric spectroscopy.
