Chrispy (Chris P.) is a scientist when he isn't writing horror stories or essaying on Lovecraft. Nanotechnology is incredible - and incredibly hard. Here, scientists have created a single-helix strand of synthesized DNA and folded the strands into a loose geometric shape and held them in place with a few short strands of DNA. By weaving many more short "staple strands" of DNA into the long strand's scaffold, Rothemund bound the DNA into a tight, mazelike pattern.
It is 100 nM wide. One of your hairs is 100,000 nM wide. A red blood cell is 10,000 nM wide.
In comparison, the smiley face on a red blood cell is like a yardstick on a football field.
