The team reports that a wisp of plastic just 50
millionths of a millimeter long behaved very much like a microscopic Slinky.
Shaping nanometric gold particles — of the size of
millionths of a millimeter — to improve their properties in biomedicine and photonics has been made possible thanks to a special laser system in a work carried out at the Universidad Complutense de Madrid (UCM) and now published in Science.
That gave him the idea for his latest project: a nano - abacus, with beads of individual molecules less than
a millionth of a millimeter wide.
«With our method, we were able to precisely measure the distance between two areas of the cytochrome to a fraction of
a millionth of a millimeter,» emphasizes Schiemann's staff member Andreas Berndhäuser.
The tiny vehicle measures only about 30 nanometers (
millionths of a millimeter).
The tracks of this cellular railway are almost unimaginably small — just 25 nanometers across (a nanometer is
a millionth of a millimeter).
The instrument uses a carefully engineered cantilever with a tip just nanometers (
millionths of a millimeter) across to scan a surface in the way the needle of a phonograph does.
Nanomaterials are named for their impossibly small dimensions, measured in nanometers (one
millionth of a millimeter).
The tip, similar to the kind used in atomic force microscopes, is attached to a bendable cantilever that controllably scans the surface of the substrate material with the accuracy of one nanometer —
a millionth of a millimeter.

In particular, this is the case for special ultra-thin glass fibers which have a diameter
of only a few hundred nanometers (one nanometer is a

of light.

millimeters thick with a magnification power
of 160 times and a resolution

of magnitude lower in cost.
