A new versatile x–y–z electrospinning equipment for nanofiber synthesis in both far and near field

Abstract

This work describes a versatile electrospinning equipment with rapid, independent, and precise x–y–z movements for large-area depositions of electrospun fibers, direct writing or assembly of fibers into sub-millimeter and micron-sized patterns, and printing of 3D micro- and nanostructures. Its versatility is demonstrated thought the preparation of multilayered functional nanofibers for wound healing, nanofiber mesh for particle filtration, high-aspect ratio printed lines, and freestanding aligned nanofibers.

Cell Electrospinning: A Mini‐Review of the Critical Processing Parameters and Its Use in Biomedical Applications

“…[35] Therefore, C-ES process should be conducted in a controlled environment that will ensure maximum cell viability while maintaining certain rheological properties. [36] The C-ES technique is still relatively new and considering that there are many parameters that affect the process, which in turn reduce the viability of the cells, it must be noted that not every condition is suitable for every procedure. Furthermore, different cell types show different resistance to applied stresses, [37,38] therefore biocompatibility remains an issue.…”

Electrowriting of SU-8 Microfibers

“…These technologies are especially adept at fabricating high-porosity materials from ultrafine- and micro-fibers [ 4 , 6 ]. MEW and SEW have similar configurations as traditional electrospinning [ 7 , 8 , 9 ], which has found widespread applications, from filtration systems to biomedical devices [ 10 ]. SEW and MEW are amenable to following AM principles, with controlled deposition of fibers, facilitating the construction of more complex, 3D multi-layered architectures [ 11 ].…”

Advances in electrospun composite polymer/zeolite and geopolymer nanofibers: A comprehensive review

“…This technique consists of forming fibers from a polymer solution, ejecting them from a fine spinneret between two electrodes bearing electrical charges of opposite polarity, one placed on the spinneret and the other on a collector. The charged solution jet evaporates during its travel towards the collector to form the nonwoven fibers' arrangement [28][29][30].…”

“…Despite being a relatively recent technique, there is a substantial body of literature that employs the electrospinning method to create diverse materials for use in a wide array of fields. For example, this method has been applied in the development of controlledrelease vitamin C capsules [30], and in consumer products such as car filters, face masks, and water filters [35], and in some of the applications of zeolite/polymer and/or geopolymer/polymer composites studied in the literature are desalination [36], filtration and dehumidification [38], medicine [39][40][41] insecticide detection [42], biofilms [43], catalysts [44], and adsorption [45], and more applications will be presented below.…”
