Among currently available nanostructured materials, ultrafine nanofibers, carrying a range of novel physical and chemical properties, have attracted considerable attention in overcoming many limitations present in their corresponding macroscales. [14][15][16][17][18][19] Different strategies have been created and developed for nanofibers fabrication, including thermal-induced phase separation, drawing, template synthesis, and self-assembly, among which electrospinning is of considerable significance as a rapid, simple, and continuous process in manufacturing nanofibers, as well as formulating their 2D and 3D structures. [20][21][22][23][24][25][26] Besides, this straightforward, continuous, and cost-effective method can launch ultrathin nanofibers from an enormous number of materials, including polymers, inorganic ceramics, and composites. [27][28][29][30][31][32] Moreover, electrospun nanofibers and their assemblies are much more favorable in providing high specific surface area, large surface-to-volume ratio, tunable porosity with uniform pores distribution, and the ability of desired chemical functionalization for various applications. [33][34][35][36][37][38][39][40] This review aims to provide comprehensive and critical aspects related to recent developments in electrospinning Electrospinning, considered as a low-cost and straightforward approach, attracts tremendous attention because nanofibrous materials with functional properties prepared by it can be widely applied in numerous fields, including rechargeable batteries, filtration, and distillation. This paper aims to provide a comprehensive review of the latest advances in developing this unique technique, which starts with a brief introduction of the advantages of electrospinning and highlights ongoing research activities, followed by its principles and progress. Afterward, the corresponding properties of electrospun nanofibers are discussed. A future vision regarding challenges and perspectives in this area is proposed at the end. It is believed that this review would provide an extensive and comprehensive reference to utilize this advanced technique to generate novel nanofibers performing in high demanding areas.

“…Generally speaking, the larger the distance, the greater the bending instability, resulting in the overlap of some nanofibers, resulting in larger fiber diameter [ 173 , 184 ]. However, if the distance is small, the solvent evaporation time is not enough, and coarse nanofibers will be formed [ 116 , 178 , 185 , 186 ].…”

“…This indicated that applied voltage could decrease the width of the printed filaments. Previous studies also indicated that a thinner Taylor cone could be achieved under a higher voltage, which can decrease line width during the printing process [19,20] . Therefore, in the following experiment, applied voltage of 4.5 kV and the coaxial nozzle with core diameter of 160 μm and sheath diameter of 500 μm were used to achieve relatively smaller filaments.…”

“…Electrohydrodynamic jetting or printing recently attracts extensive attentions in fabricating highresolution features based on the principle of elec tro hydro dy namically induced material flows [12][13][14][15][16][17][18] . Several process parameters had been investigated to achieve stable electrohydrodynamic printing process, such as applied voltage, moving speed, feeding rate of materials and inter diameter of nozzle [19][20][21][22][23][24][25][26] . Recent explorations indicate that biomaterials like living cells and hydrogels can be electrohydrodynamically printed and maintained their viability [27][28][29][30] .…”

Cell printing has found wide applications in biomedical fields due to its unique capability in fabricating living tissue constructs with precise control over cell arrangements. However, it is still challenging to print cell-laden 3D structures simultaneously with high resolution and high cell viability. Here a coaxial nozzle-assisted electrohydrodynamic cell printing strategy was developed to fabricate living 3D cell-laden constructs. Critical process parameters such as feeding rate and stage moving speed were evaluated to achieve smaller hydrogel filaments. The effect of CaCl 2 feeding rate on the printing of 3D alginate hydrogel constructs was also investigated. The results indicated that the presented strategy can print 3D hydrogel structures with relatively uniform filament dimension (about 80 μm) and cell distribution. The viability of the encapsulated cells was over 90%. We envision that the coaxial nozzle-assisted electrohydrodynamic printing will become a promising cell printing strategy to advance biomedical innovations.
