- Longest DNA, nanotube, polymer, silk, nylon, glass, wire
Main Question or Discussion Point
What is the longest molecule? Are we talking about of order of magnitude:
- 1 metre, eg. DNA, carbon nanotube, polyethylene (UHMWPE)?
- 1 kilometre, eg. silk strand, monofilament nylon?
- 100 to 1,000 km, eg. steel wire for suspension bridge, copper wire, optical glass fibre?
- 12,700 km, covalent bonding connecting the whole of the Earth's crust?
