A group of Krasnodar State University alumni in Russia’s Black Sea region has developed efficacious nanosized filaments to be used in medical masks and in disposable filters for respirators.

The team started by experimenting with kerosene soot particles which are the size of the coronavirus. Also, the conventional fabric typically used in medical masks was checked for saturability, and compared with the new nanosized filaments. The new fibers were reported to be more helpful in keeping off the coronavirus than the conventional ones.

The new fibers could also be used to make water purification and desalination systems.
