Despite measuring 10,000 times
less than the diameter of a human hair, the new muscles can lift more than 100,000 times their own weight, which amounts to approximately 85 times the power of a natural muscle of equivalent size.
One of the most widely used methods in this field is called «DNA origami» which allows to fabricate nanoparticles with almost arbitrary shapes, which are around a thousand-fold
smaller than the diameter of a human hair.
«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.
This thermal ratchet is made from a material known as «artificial spin ice» which comprises of a number of tiny nanomagnets — made of the nickel - iron alloy Permalloy and which are 200 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.
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.
These particles are smaller
than the diameter of a human hair but frequently caused haze in the cities.
Individual nanotubes can be 10,000 times smaller
than the diameter of a human hair, yet 100 times stronger than steel, pound - for - pound
