article imageNew laser spinning method produces bioactive glass nanofibers

By Elizabeth Cunningham Perkins     Dec 18, 2009 in Science
Using a unique laser spinning technology, researchers have produced nanofibers made of the bioactive glass used for regenerating bone. According to the scientists, their method allows the manufacture of new, otherwise impossible nanofiber compositions.
An international research team from the University of Vigo in Spain, Imperial College London in the United Kingdom and Rutgers University in the United States has announced the development of an innovative process for constructing glass nanofibers.
The team reports successful production of flexible, continuous bioglass composition nanofibres, a bioactive glass that can help bone cells regenerate.
FĂ©lix Quintero, co-author of the study and a researcher at the University of Vigo, said that the team's new laser spinning technique is simple, yet allows both a high rate of production and better control over the composition of the material. The method involves using a high-energy laser to melt small amounts of a precursor material to create super-fine filaments that are lengthened and cooled by powerful jets of gas, he explained.
Quintero's team is now researching ways to use laser spinning to manufacture other biomedical nanofiber compositions, as well as composite materials for other fields that require nanofiber reinforcement, such as CO2 capture systems and fire-retardant fabrics.
The team's research has been published in the Oct. 9 issue of Advanced Functional Material.
