How can you describe a nanoparticle?
A nanoparticle can only be seen under an electron microscope, nanoparticles measure from 1 to 100 nanometres. For comparison, the diameter of a hair is 40 to 100 micrometres and 1 micrometre is 1000 nanometres. So the diameter of a hair is equivalent to between 40,000 and 100,000 nanoparticles.
What is it like to work with something that small in the lab? How do you research them?
We work with very large numbers and observe them as white or coloured powder, which is actually just a big bunch of nanoparticles. When we...
