ITHACA, N.Y. -- A new understanding of how large biological molecules behave in tiny spaces could lead to a method for separating DNA strands by length. It also could throw light on the way molecules move in living cells. Using a forest of nanofabricated pillars so small that DNA molecules can only slip through lengthwise, Cornell University researchers have demonstrated the existence of an entropic recoil force that causes the molecules to move from a tight space into a more open one.
The above story is based on materials provided by Cornell University. Note: Materials may be edited for content and length.
