Uses cylindrically-shaped colloidal metal nanoparticles. In which the metal composition can be alternated along the length and the size of each metal segment can be controlled. Intrinsic differences in reflectivity between the metal segments allow individual particles to be identified by conventional optical. Microscopy. See surromed and Penn State. In the Journal Science. Uses cylindrically-shaped colloidal metal nanoparticles. Microscopy. See surromed and Penn State. In the Journal Science.

Dictionary of nanotechnology - Atomic Force Microscopy
http://www.nanodic.com/Nanocharacterization/Atomic_Force_Microscopy.htm
A microscope that uses a tiny probe mounted on a cantilever. To scan the surface of an object. The probe is extremely close to-but does not touch-the surface. As the probe traverses the surface, attractive and repulsive forces arising between it and the atoms. On the surface induce forces on the probe that bend the cantilever. The amount of bending is measured and recorded, providing a map of the atoms. Sufficient to resolve individual carbon. Also called scanning force microscope. Type of scanning probe...

http://www.nanodic.com/Carbon/Buckminsterfullerene.htm
Buckminsterfullerene (IUPAC name (C60-Ih)[5,6] fullerene. Is the smallest fullerene. In which no two pentagons share an edge (which can be destabilizing; see pentalene). It is also the most common in terms of natural occurrence, as it can often be found in soot. In the structure of a soccer ball (12 pentagons and 20 hexagons). A sphere of sixty carbon. Also called a buckyball. Named after the architect Buckminster Fuller, who is famous for the geodesic dome. A broad term covering the variety of buckyballs.
