NANOFIBER MATRICES FORMED FROM ELECTROSPUN HYPERBRANCHED POLYMERS

摘要

A nanofiber matrix comprising an active agent suspended or enmeshed in fibers formed by the electrospinning of one or more hyperbranched polymers can be used in cosmetics, drug delivery and for the growth of cells. The process of electrospinning the hyperbranched polymer solution is carried out without an added solvent or with a solvent and a compressed gas.
