«That means things that are
smaller than the diameter of a human hair, like cells, parts of cells or the fine structure of fibers.»
They also tracked Apolipoprotein E (APOE 4), a well - known genetic risk factor for Alzheimer's, as well as lifetime cumulative exposure to unhealthy levels of PM2.5 — particles which are at least 30 times
smaller than the diameter of a human hair and frequently cause the haze over urban areas.
One particle is only 500 nanometers in size, which is 150 times
smaller than the diameter of a human hair.
In the center is a hole poked through the metal layer with a diameter of about 300 nanometers — about 1,000 times
smaller than the diameter of a human hair.
For example, using a specially developed patterning technique, they wrote the word, «ICE,» on the material in a physical space 10 times
smaller than the diameter of a human hair.
Although the tiny particles are around ten thousand times
smaller than the diameter of a human hair, the surface area of a kilogram of such particles is equivalent to that of several football fields.
Individual nanotubes can be 10,000 times
smaller than the diameter of a human hair, yet 100 times stronger than steel, pound - for - pound

of a
human hair), while they can be up to several millimeters in length.
