If you had to grasp a tiny delicate object such as a blood vessel, doing so with traditional tweezers would be a very painstaking process – just a little too much pressure, and the object could be crushed. Instead, scientists from Iowa State University have developed miniature coiling tentacles for doing the job. They're even capable of holding an ant without harming it.
The tentacles are actually microtubes measuring just 8 mm long by about a quarter of a millimeter across, that are composed of polydimethylsiloxane (PDMS) elastomer.

You know the Japanese anime crowd are going to love this tech.
