nano spaghetti to the rescue

Behold the world’s thinnest spaghetti The 'nanopasta' is 200x thinner than a human hair. ]

This nanofiber is about 200 times thinner than a human hair and was created by a team at University College London (UCL). While it won’t be making its way onto the menu of an Italian restaurant anytime soon, this creation was cooked up in a lab because nanofibers have wide applications in medicine and industrial design.'' To do this, they used a technique called electrospinning. '

An electric charge pulls threads of flour and liquid through the tip of a needle. in the journal Nanoscale 

Advances.Earthcom article notes:The microscopic mats of nanofibers are permeable enough to permit the passage of water and moisture, while acting as a protective barrier against harmful bacteria.
