Schematic of electrospinning equipment and the resultant fibers and therapy loaded variants. The electrospinning set-up comprises a high voltage (V) supply which is connected to a syringe loaded with a polymer solution. Within the blending technique therapeutics or therapeutic precursors are mixed with polymer solutions before electrospinning. Either co-axial or emulsion electrospinning produces core/shell morphology fibers. This method allows for the encapsulation of therapeutics in either layer. Therapeutic attachment to fibers post-electrospinning allows for the loading of fragile molecules which cannot endure the electrospinning process.
