Researchers from University College London have the world's thinnest spaghetti. It about 200 times thinner than a human hair. The pasta strands so thin they cannot captured in a photo. Nor can they seen with the naked eye or through a microscope. The nano-spaghetti is just 372 nanometres wide. That's equivalent to millionths of a centimetre. The spaghetti was using a technique electro-spinning. In this procedure, an electric charge a mixture of flour and liquid through microscopic holes. Professor Gareth Williams said: "I don't think it's useful as pasta, sadly, as it would in less than a second, before you could it out of the pan."

The new spaghetti will largely used for medicinal rather than culinary purposes. However, Dr Adam Clancy said it is edible. He said: "Hypothetically, one might it to be chewier than you'd expect". Individual strands of the nanopasta can be into a pasta net. This could be as a scaffold for regrowing tissue. The net could also be used to bandages that would help wounds . The bandages would moisture through to the skin, but keep bacteria out. They could also bone regeneration and drugs to different parts of the body. The scientists say there also non-medicinal applications, such as its use in filtration systems and batteries.
