Electrospinning is a versatile method of producing micro- and nanofibers deposited in mats used as scaffolds for tissue engineering. Depending on the application, single or coaxial electrospinning can be used. Coaxial electrospinning enables the use of a broad spectrum of materials, the fabrication of hollow or core/shell fibers and an automatisation of the entire electrospinning process. In this regard, the design of coaxial nozzles plays a major role in a standardized as well as tailor-made scaffold fabrication. For this purpose an optimised coaxial nozzle has been designed and fabricated. Furthermore, tests have been carried out to validate the new nozzle design. With the use of the costum-made nozzle polymer concentration could be varied in a gradual manner. The variation in polymer concentration lead to fiber diameters between 0.75 to 3.25 μm. In addition, an increase in rotating velocity lead to an increase in fiber alignment as well as a slight decrease in fiber diameter. The demonstrated modifications of coaxial electrospinning proved to be a powerful tool for in-process adjustments of scaffold fabrication.
