Laser Technique Creates Micro-Structures on a Human Hair

From Science Daily:

Shown in this image are electron microscopy images at increasing magnification of a representative structure created on a human hair.

The strokes on the letters are more than 20 times smaller than the diameter of the hair. The researchers can readily create structures with features that are more than ten times smaller, which further suggests that it may ultimately prove possible to use this technique to create functional structures directly on single cells.
