Researchers from University College London have created the world's thinnest spaghetti. It is about 200 times thinner than a human hair. The pasta strands are so thin they cannot be captured in a photo. Nor can they be 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 made using a technique called electro-spinning. In this procedure, an electric charge pushes 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 overcook in less than a second, before you could take it out of the pan."

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