Knots are everywhere—from tangled headphones to DNA strands packed inside viruses—but how an isolated filament can knot ...

Nanotechnologies require a detailed knowledge of the molecular state. For instance, it is useful to know when and how a generic polymer, a long chain of polymers (chain of beads), knots. The study of ...

Knot theory provides a rigorous mathematical framework to classify and study the entanglements that occur in polymer systems. By applying topological methods, researchers can decipher how knots and ...

Biocompatible complexes for drug delivery applications get a structural boost from nanoscale silicon cages. Protein-based drugs show promising activity against many hard-to-treat targets. Getting ...

Heralding the era of new generation advanced materials which are super strong, flexible, and elastic, the University of Manchester broke many world records in science with its team of chemical ...

Polymer fluids are made of long chains of atoms. Scientists have used simulations to discover a special polymer liquid that takes this behavior to the extreme. When researchers elongate necklace-like ...

Turning the art of a trefoil knot into polymer science is no easy process, but researchers at Case Western Reserve University developed a technique that produces a long chain molecule with the desired ...

(Nanowerk News) Plastics or DNA: Many molecules are so long that they can form knots, much like tying shoes. Whereas it is still disputed whether right- and left-handed people prefer to tie their ...

Scientists at MIT say they have discovered the factors that determine whether a DNA knot moves along the strand or “jams” in place. The findings could help researchers develop ways to untie DNA knots, ...

Researchers have used a new biodegradable material to make surgical sutures that knot and tighten themselves as they warm to body temperature. The new material could help surgeons working in tight ...
