Of bio-hairpins and polymer-spaghetti: Spotlight on how entangled polymers flow and soften

9 octubre 2014

When a basically sturdy material becomes soft and spongy, one usually suspects that it has been damaged in some way. But this is not always the case, especially when it comes to complex fluids and biological cells. By looking at the microscopic building blocks — known as «filaments» — of biopolymer networks, researchers have evealed that such materials soften by undergoing a transition from an entangled spaghetti of filaments to aligned layers of bow-shaped filaments that slide past each other.
