Non-toxic Nanofibers: New Approach Expands Polymer-based Fiber Use

Pictured above are very small fibers (red) that make up the non-toxic fabrics developed at UMass Amherst in comparison to a human hair (gray). The salt crystals, shown in white, seen on the surface of the fibers can easily be rinsed away using water. Chemical engineers Jessica Schiffman and Sarah Perry have developed nanofibers that are both green and non-toxic that can be used in medical, environmental, personal care and food packaging applications. Unlike traditional methods that use toxic organic solvents, their non-toxic approach to making polymer-based fibers uses polymers that assemble to form fibers from a solution of water and salt.
