Tying Molecules In Knots

Posted by samzenpus on from the nimble-fingers dept.

Med-trump writes "Scientists report that they have made a non-DNA molecular knot. They created a 160-atom-loop with five crossing points, a molecular pentafoil knot. The researchers used a technique known as 'self-assembly' to prepare the knot in a chemical reaction. Apparently 85% of the elasticity of natural rubber is due to knot-like entanglements in the rubber molecules' chains."

    Yours was actually the second post.
    You got the first failure, though.

    It took me long enough to learn how to tie my shoes. I hope this won't be on the final exam.

    Actually naturally-occuring protein knots have been known for some time now. See knots.mit.edu for example. This appears to be one of the first synthetic knots.

    You do know that "self-assembly" isn't really a technique. That's like writing that Google updated their search algorithm using a technique known as "writing code". Self-assembly is just a term for things that assemble by themselves.
