SOF4-derived polymer Structure (IMAGE) Cold Spring Harbor Laboratory Caption Chemical structure and models of the SOF4-derived polymer. On the left, a side view shows how the monomers link together to form a twisted polymer. On the right, a view looking down the shaft of a tiny polymer fiber shows that it coils into a helix with a hollow center. Credit Sidharam P.
