Scientists have created spaghetti that's 200 times thinner than a human hair, but it's not intended for eating.

Researchers are exploring the potential applications of a new material.

A significant number of scientific studies focus on medicine: the study of stem cells, the use of robots to deliver medications directly to affected organs, and so on. In this pursuit, researchers are attempting to invent or rediscover materials that could prove useful.

For instance, a group of researchers has created the thinnest spaghetti in the world; however, it is not meant to delight the taste buds. They produced ultra-thin strips made of starch—approximately 200 times thinner than a human hair—known as nanofibers for use in medicine and industry.

Starch is produced by most green plants to store excess glucose. Dressings made from starch nanofibers can be used for wound healing—they are highly porous, protect against bacteria, and allow water to pass through. They can also be utilized for bone regeneration and even drug extraction. Nanofibers made from starch can aid in the recovery of bones or other tissues because they "mimic the extracellular matrix—a network of proteins and other molecules that build cells to sustain themselves."

Researchers proposed several methods for creating such dressings, but the most environmentally friendly and cost-effective involves using regular flour as a starch-rich ingredient, the same kind of flour used in actual spaghetti. The process of creating nanofibers resembles making pasta—flour was mixed with water and extruded through a narrow metal opening, powered by electricity. From the new fibers, they created a piece of fabric approximately 2 cm long.

Another unique aspect of using starch is that it is the second-largest source of biomass on Earth after cellulose, and it can decompose within the body when necessary.

Previously, "Telegraph" reported on another discovery, but not at the nanoscale; instead, it was in the depths of space. Scientists managed to photograph the first star beyond our galaxy.
