About Levan: References

Levan has long fascinated researchers as shown by numerous papers describing successful laboratory studies. Until now, those ideas have been largely unrealized, at least partly because the polymer was so expensive in gram quantities. Our research has made possible large scale production and availability at a reasonable price.
