Gold-tipped CdSe/CdS Nanorod, STEM
Z-contrast image of a gold-tipped CdSe/CdS nanorod measured by HAADF mode in Scanning TEM (70 x 70nm). An annular dark field image formed only by very high angle, incoherently scattered electrons is highly sensitive to variations in the atomic number of atoms in the sample (Z-contrast images). This technique is also known as high-angle annular dark-field imaging (HAADF). In nanotechnology, nanorods are one morphology of nanoscale objects. Each of their dimensions range from 1-100 nm. They may be synthesized from metals or semiconducting materials. Nanorods are produced by direct chemical synthesis. Nanotechnology (nanotech) is the manipulation of matter on an atomic, molecular, and supramolecular scale.
