“…[23][24][25] David et al 26 increased the level of production by using two metal plates to form a gap that replaces the traditional capillary needle by simultaneously provoking numerous polymeric jets from an adequate liquid surface area. Park et al 27 achieved the spinning of 5 jets using a coaxial grooved nozzle and two uids, resulting in superior ber morphology. In 2007 Liu and He proposed a large-scale bubble spinning preparation that is suitable for commercial production.…”

A modified bead structure nozzle for the electrospinning process was developed to improve the production efficiency of nanofibers and facilitate the cleaning of equipment. The effects of the flow rate, voltage and receiving distance on the number of jets were studied. The results indicate that the number of stable jets can be effectively controlled by spinning conditions. The rotating spinning phenomenon, which occurred during spinning, was subjected to force analysis. The COMSOL Multiphysics model was applied to simulate the electric field to show that the bead structured nozzle does not change the overall spinning electric field compared with traditional spinning. The results indicate that the bead structure nozzle can produce a stable multi-jet using a curved surface structure and improve the production efficiency of nanofibers. Compared with the high-voltage conditions of needleless spinning, the beadtype nozzle helps to save energy and facilitate cleaning, so as to avoid the production of waste in experimental research and industrial production.

Unique features of nanofibers provide enormous potential in the field of biomedical and healthcare applications. Many studies have proven the extreme potential of nanofibers in front of current challenges in the medical and healthcare field. This review highlights the nanofiber technologies, unique properties, fabrication techniques (i.e., physical, chemical, and biological methods), and emerging applications in biomedical and healthcare fields. It summarizes the recent researches on nanofibers for drug delivery systems and controlled drug release, tissue‐engineered scaffolds, dressings for wound healing, biosensors, biomedical devices, medical implants, skin care, as well as air, water, and blood purification systems. Attention is given to different types of fibers (e.g., mesoporous, hollow, core‐shell nanofibers) fabricated from various materials and their potential biomedical applications.

Electrospinning procedures such as blend electrospinning, coaxial electrospinning, and emulsion electrospinning have been used for the fabrication of electrospun nanofibers (ENFs) for biomedical applications. These ENFs are attracted great interest especially in drug delivery applications due to their small size, high surface area‐to‐volume, and porosity. The aim of this review is to focus on the controlled release mechanism among the different electrospinning methods, and the selectivity of hydrophilic, water‐soluble polymers as a carrier for drug. The mechanism for the drug delivery depends mainly on the method of drug loading, polymeric interactions, and the nature of polymer swelling, erosion, or degradation. This review compressed on the literature survey about the fabrication of nanofibers by different electrospinning methods, factors affecting the nanofiber morphologies, selectivity of polymeric blends for successful controlled release behavior, and the mechanism involved in the drug release steps.
