Functional polymeric micro/nanofibers have gained considerable interest as promising materials for the structures that are potentially beneficial in lot of application areas as they possess excellent characteristics such as large surface-area-to-volume ratio, incredibly small pore dimensions etc. Microfluidic developments have currently shown a huge amount of opportunities as revolutionary approaches to create microfiber. By carefully regulating the flow and reaction kinetics in microchannel chip, microfluidic-spinning technology can be applied to generate fibers with tailored characteristics and polymorphic structures. However, this paper features the basic mechanism of micro-fiber production by microfluidic spinning Technology (MST) as well as the principle of Elcectro-Microfluidic Spinning Technology (EMST). Besides, core-shell fiber production by MST is also described in brief. Finally, the advantageous features, application areas and challenges of MST are reviewed briefly in this paper.

Microfluidics has gotten a lot of attention from scientists and engineers in a variety of fields [1]. Microfluidics is described as the design or application of devices that apply fluid flow to channels that are smaller than 1 millimeter in at least one dimension [2]. It is also named as miniaturized total (chemical) analysis system (μTAS) [3]. To create microscale liquid structures, this method allows for versatile and precise manipulation of the flow and dispersion of several liquids in microchannel [4]. It’s a promising method for using small amounts of materials in a variety of applications, including biomedical and energy devices [5].

Micro/nano fibers are ubiquitous, whether in nature or modern industry [6]. Polymeric fibers are gaining popularity due to their unique properties, including a high surface area to volume ratio, versatility in surface functionalities, and superior mechanical performance (e.g., stiffness and tensile strength) when contrasted to any other known material type [7]. Energy conservation, tissue engineering, pollutant separation and wound healing are only a few of the applications for functional microfibers [4]. Encapsulating cells on microfibers, for example, provides a simple three-dimensional (3D) model for cell culture and the development of complex tissues [8]. Spinning methods, however, have received a lot of attention among the various technologies for producing polymer fibers [9].

Microfibers are being made from a variety of materials using traditional fabrication methods such as electrospinning and wet spinning, but producing microfibers with controllable internal microstructures remains a challenge [4]. The majority of microfiber production techniques have a homogeneous chemical composition and structures that vary significantly from those found in human tissues. Other spinning methods’ limitations have prompted researchers to develop new techniques for producing fibers with a topographical architecture that more closely resembles the complex structures and functions of living tissues or organs [10]. Furthermore, they are generally compatible with a limited range of materials and often necessitate a lengthy processing method, both of which severely limit their applications [11]. Microfluidic Spinning Technology (MST) has recently risen to prominence as a simple method for creating orderly diverse structures, controllable compositions, and well-organized functions [12].

Knowledge of technology and engineering is the fuel for creativity and success. A spinner must therefore be technologically aware, efficient, flexible, and cost conscious. From this perspective, it is attempted to make an overview of mechanism of microfluidic spinning technology (MST). Besides, mechanisms of co-axial and electro microfluidic spinning systems are also given briefly in this paper. After that, the advantages of this spinning system for microfiber production have been described.

Microfluidic Spinning Technology (MST)

Microfluidic spinning technology (MST) is a technique inspired by the natural phenomenon of spiders or silkworms spinning silk [8]. It can also be stated as the type of Solution Blow Spinning (SBS) system. However, microfluidic spinning (Figure 1), a combination of wet spinning and microfluidic technology, has been used to produce microfibers with unique structures [13].
