Coaxial electrospun nanostructures and their applications

Pharmaceutical Applications of Electrospraying

“…5 A large number of advanced applications for polymers, environmental protection, sensors, energy storage, tissue engineering, and drug delivery based on electrospinning can be found in literature. [6][7][8][9] Nevertheless, also electrospraying has begun to gain more attention as evidenced by its rapidly growing literature. Reasons for the recent focus on electrospraying, arguably one of the most promising, efficient, and well-practiced techniques to generate particulate materials for pharmaceutical and biomedical applications, is that it has several key advantages over other techniques to produce particles, which can be summarized as follows:…”

Flexible hollow nanofibers: Novel one-pot electrospinning construction, structure and tunable luminescence–electricity–magnetism trifunctionality

“…This method not only attracts extensive academic investigations, but is also applied in many areas such as filtration [47], luminescent materials [48,49], biological scaffolds [50], electrode materials [51] and nanocables [52]. Recent efforts have been made to improve electrospinning method and setup, and nanofibers with novel structures, such as coresheath, Janus, porous and hollow morphology, can be prepared if appropriate processing parameters are adopted [53][54][55][56][57][58]. In many cases, nanofibers with hollow structure were prepared by coaxial electrospinning technique, in which coaxial spinnerets replace the single spinneret in the conventional setup for electrospinning, followed by appropriate post-treatment, such as core solvent extracting or calcination process.…”

Electrospinning of natural polymers for advanced wound care: towards responsive and adaptive dressings

“…In the first case, an example of modified ES process is coaxial electrospinning, where multiple spinnerets are used to produce core-shell structures or multichannel nanotubes. 45 In the second case, collectors (disks, cylinders, patterned elements) that can rotate at specific speed offer the possibility to achieve a good degree of alignment of the electrospun fibres ( Figure 2e). 32,46 High surface-to-volume ratio, porosity and threedimensional (3D) organisation make electrospun mats relevant for diverse applications, such as filtration, sensors, energy and catalysis; 43,47,48 but it is for tissue engineering that those characteristics become crucial.…”
