Characterization of spherical and rod shaped gold engineered nanomaterials (ENMs, nanometer (nm)), representative of both positively and negatively charged ENMs which were selected to be identical other than their surface charge. ENMs were characterized using dynamic light scattering (DLS), disc centrifugation sedimentation (DCS), transmission electron microscopy (TEM) and ultraviolet-visible (UV-Vis) absorption spectrometry.
