Molecularly designing polymer networks to control sound damping

The world is filled with myriad sounds and vibrations—the gentle tones of a piano drifting down the hall, the relaxing purr of a cat laying on your chest, the annoying hum of the office lights. Imagine being able to selectively ...

DNA design brings predictability to polymer gels

Scientists in Japan have made a tuneable, elastic and temperature-sensitive gel by using complementary DNA strands to connect star-shaped polymer molecules together. The gel, and the method used to develop it, could lead ...

A record-long polymer DNA negative

A fragment of a single strand of DNA, built of the nucleobases cytosine and guanine, can be imprinted in a polymer—this has been shown by chemists from Warsaw, Denton and Milan. The resulting artificial negative, with a ...

Tests show 'crystalsome' nanoparticle lasts longer in bloodstream

Selecting the right packaging to get precious cargo from point A to point B can be a daunting task at the post office. For some time, scientists have wrestled with a similar set of questions when packaging medicine for delivery ...

Using DNA strands to design new polymer materials

McGill University researchers have chemically imprinted polymer particles with DNA strands - a technique that could lead to new materials for applications ranging from biomedicine to the promising field of "soft robotics."

Molecular knot wins record for 'world's tightest'

Scientists at The University of Manchester are celebrating after becoming record breakers and officially being awarded a Guinness World Record for tying the tightest knot ever produced.
