The width of two ridges of a human latent fingerprint is approximately 1 mm (millimeter). Let's convert that to nanometers.
1mm X 1,000 = 1,000mm (microns)
1,000mm X 1000 = 1,000,000 nanometers
What is the size of one nanometer?
Answer: ten hydrogen atoms lined up side by side
Nanotechnology is here. Welcome to my first adventure in this emerging technology!
