Researchers in the U.K. have made the world's thinnest spaghetti. The "nano-spaghetti" is 372 nanometres wide – 200 times thinner than a human hair. It cannot be captured in a photo, nor be seen with the naked eye, nor be viewed through a microscope. The spaghetti was made using a technique called electro-spinning. This uses electricity to push a flour liquid through microscopic holes. A researcher said it would overcook in a pan in less than a second.

The new spaghetti will be largely used in medicine rather than for cooking, even though it is edible. Individual strands of the spaghetti can be made into a pasta net. This could help to regrow tissue and bone. It could also be used for bandages to help wounds heal. The bandages would keep bacteria out. The researchers say there are also non-medicinal applications. These include uses in filtration systems and batteries.
