“…This lets nanoparticles of a multitude of footprints accumulate into a tight scaffold, which only increases in height while maintaining constant lateral size. This mechanism is in great contrast to that of cone-jet printing in which the ink and the accompanying nanoparticles continuously spread on the substrate owing to the high immediate volume flow rates 7,8 .…”

“…The only purpose of using pulses is to precisely control the number of deposited droplets, that is, nanoparticles, and therewith the extent of printed nanostructures. It is worth stressing that our terminology of a pulse should not be confused with that of pulsed EHD jet-type processes reported by other authors 7,8 . In these studies, the pulse duration is related to the amount of liquid accumulated on the substrate, and is therefore an important process parameter affecting the lateral size of printed structures, after evaporation of the accumulated liquid.…”

Direct printing of nanostructures by electrostatic autofocussing of ink nanodroplets

nanotechnology, with its broad impact on societally relevant applications, relies heavily on the availability of accessible nanofabrication methods. Even though a host of such techniques exists, the flexible, inexpensive, on-demand and scalable fabrication of functional nanostructures remains largely elusive. Here we present a method involving nanoscale electrohydrodynamic ink-jet printing that may significantly contribute in this direction. A combination of nanoscopic placement precision, soft-landing fluid dynamics, rapid solvent vapourization, and subsequent self-assembly of the ink colloidal content leads to the formation of scaffolds with base diameters equal to that of a single ejected nanodroplet. The virtually material-independent growth of nanostructures into the third dimension is then governed by an autofocussing phenomenon caused by local electrostatic field enhancement, resulting in large aspect ratio. We demonstrate the capabilities of our electrohydrodynamic printing technique with several examples, including the fabrication of plasmonic nanoantennas with features sizes down to 50 nm.

“…The concentration of silver nanowires and the fl ow rate were critical parameters for the width and uniformity of the e-jet printed lines. Silver nanowires aligned within the printed lines as a result of the fl ow and electrical fi eld as shown in Figure 18 b. Stark and Wang [ 145,233 ] explored e-jet printing of spherical gold nanoparticles with diameters of 10 nm and found that particles form clusters within the printed spots as shown in Figure 18 c. These clusters likely form due to capillary interactions between the particles during the evaporation of water. Such colloidal assemblies can be useful in photonic crystals with multiple wavelength bands as recently demonstrated with ink-jet printing.…”

This review gives an overview of techniques used for high-resolution jet printing that rely on electrohydrodynamically induced flows. Such methods enable the direct, additive patterning of materials with a resolution that can extend below 100 nm to provide unique opportunities not only in scientific studies but also in a range of applications that includes printed electronics, tissue engineering, and photonic and plasmonic devices. Following a brief historical perspective, this review presents descriptions of the underlying processes involved in the formation of liquid cones and jets to establish critical factors in the printing process. Different printing systems that share similar principles are then described, along with key advances that have been made in the last decade. Capabilities in terms of printable materials and levels of resolution are reviewed, with a strong emphasis on areas of potential application.

“…Among them, the cone-jet mode (axial mode III) in the atomisation regime has been extensively studied for the deposition or printing purpose in electrospray (ES) technology [7][8][9][10][11]. By modulating voltage a dropon-demand capability of placing tiny solution with a good accuracy was demonstrated [12,13]. Also, periodically formed transient-jet in the pulsation mode has been proposed to be used to create patterns or microstructures [14][15][16].…”
