• not been solved [4]. Needle-free electrospinning devices fundamentally solve the needle blockage problem and can prepare micro/nanofibers more effectively [5]. With the expanding application field of electrospun nanofibers and the change of human needs, various functional nanofibers have emerged as

• ; nanofibrous carriers; needle-free electrospinning; release kinetics; Introduction To date, numerous drug delivery systems have been developed, such as hydrogels that carry drugs or highly sophisticated electronic microchips [1][2]. The required release rates of the therapeutic agents depend on the medicinal

The needle-free electrospinning process was optimized for each type of nanofiber with respect to the different physicochemical properties of polymers. SEM images revealed that the textures of all resultant samples were homogenous and free

• the thickest, with a diameter of 282 nm. The surface areas corresponded to the fiber diameters; the surface area was largest for the thinnest PVA fibers (7.7 m2/g) and smallest for PLA (4.7 m2/g). These differences are due to the needle-free electrospinning method. Needle-free electrospinning does not
