  • The world’s thinnest spaghetti, about 200 times thinner than a human hair, has been created by a UCL-led research team.

    

    The spaghetti is not intended to be a new food but was created because of the wide-ranging uses that extremely thin strands1 of material, called nanofibers, have in medicine and industry.

    Nanofibers made of starch2 – produced by most green plants to store excess glucose3 – are especially promising4 and could be used in bandages to aid wound healing (as the nanofiber mats are highly porous5, allowing water and moisture in but keeping bacteria out), as scaffolding for bone regeneration and for drug delivery. However, they rely on starch being extracted from plant cells and purified, a process requiring much energy and water.

    

    A more environmentally friendly method, the researchers say, is to create nanofibers directly from a starch-rich ingredient like flour, which is the basis for pasta.
