Nanofabrication of Janus Fibers through Side-by-Side Electrospinning - A Mini Review

Abstract

Janus and core-shell nanostructures are the most fundamental structural characteristics for comprising all types of multiplechamber structures. The facile preparation of Janus structure is one of the most difficult challenges in the field of nanofabrication, whose production can pave a broad way for generating a wide variety of hierarchic nanostructures. Based on several most recent reports, this mini review provides some comments on the generation of Janus nanofibers on the following topics: (1) the key points for fabricating Janus nanofibers using side-by-side electrospinning; (2) the strategies for functionalizing the Janus nanofibers; and (3) the possibilities of complex nanostructures started from the two-chamber Janus structures.

Functionalized Antimicrobial Nanofibers: Design Criteria and Recent Advances

“…Co-axial electrospinning uses two nozzles containing the polymer solution and the therapeutic agent separately, to produce a core-shell structure in the nanofibers [ 134 , 135 , 136 , 137 ]. Usually, the polymer matrix will provide the outer core, while the therapeutic agent is incorporated in the inner core of the nanofibers [ 27 , 138 ]. Recently, researchers have shown an effort to develop 3D electrospun polymeric nanofiber scaffolds using several combinations of techniques such as co-axial electrospinning with add-on techniques such as electrospraying, 3D printing, gas foaming, freeze-drying, and centrifugal electrospinning, to obtain multifunctional structures.…”

Effective Conduction of University Safety Education in Scientific Practices Through an Integrated Manner

“…Electrospinning is an electrohydrodynamic atomization methods, just as electrospraying [1][2][3][4]. It takes the advantages of the easy interactions between the working fluids with the electrostatic high voltage energy [5][6][7][8][9]. Thus, on one hand, several methods have been reported to how to save energy for production [10,11].…”

“Scientific Research Nurtures Teaching” Based on Coaxial Electrospraying

“…Among all types of advanced materials production methods, electrospraying is a popular one, which is easy to implement and effective in creating polymeric particles with a size from several decades of nano meters to several microns [1][2][3][4]. Electrospraying and electrospinning are two most important branches of electrohydrodynamic atomization (EHDA) methods, which takes the advantages of the easy interactions between the working fluids and the electrostatic energy [5][6][7][8][9][10]. After the popularity of electrospinning during the past three decades for creating a series of structural nanofibers, including core-shell [11], homogeneous [12][13][14], side-by-side [15,16], tri-layer coreshell [17] and other complicated multiple-chamber ones [18], electrospraying is also becoming more and more popular in the laboratory experiments and also potential industrial applications.…”
