“…[1][2][3][4][5] Particularly in this nano era, nanotechniques and the corresponding complex nanostructures they produce continuously exhibit the capability to generate novel nano-drug delivery systems (DDSs). [6][7][8][9] The three directions of nanoscience, i.e., "small size, order, and structure", aim to produce all kinds of nanomaterials with increasingly smaller sizes to create arrays of nanoproducts for functional applications and to generate new complicated nanostructures and nanodevices for tailoring functional performances. [10][11][12][13] Along these directions, electrohydrodynamic atomization (EHDA) techniques (mainly including electrospinning, electrospraying, and e-jet printing) are continuously contributing to the generation of new types of functional nanomaterials for applications in almost all applied scientific fields such as energy, environmental science, and medicine.…”
