“…This extra step is time consuming, inconvenient and results in additional thermal budget but more importantly, could preclude the use of delicate substrates depending on the annealing temperature. In contrast, combining cold plasma with aerosol delivery of the ink/nanoparticles can eliminate the need for the secondary annealing step [31][32][33] and also, the use of atmospheric pressure plasma in the form of a dielectric barrier discharge (DBD) eliminates the need for the expensive vacuum chamber construction and vacuum pumps, thus simplifying the overall system. The characteristics of the plasma jet can be exploited to tailor the properties of the materials passing through it.…”

An atmospheric pressure plasma based printer is described as an alternative to conventional techniques including inkjet printing. The approach is demonstrated to be capable of printing various nanomaterials, and adjusting the plasma parameters, carrier gas flows and the physical parameters of the inks or nanomaterial suspensions can optimize the print quality. Raman analysis was used to characterize the oxide materials and carbon nanotubes printed using this technique, revealing high quality prints. The printed carbon nanotubes were used in a gas sensor chip and shown to provide good ammonia detection capability.

“…Patterned-wettability technology is important for manipulating fluid on a surface and applications [21][22][23][24]. Among different patterning techniques, atmospheric-pressure plasma jet (APPJ) has been demonstrated as an efficient tool for patterned modifications on different surfaces, such as polycarbonate (PC) [25], polypropylene (PP) [26], polyethylene terephthalate (PET) [27], polymethyl methacrylate (PMMA) [28], polydimethylsiloxane (PDMS) [29] and even metallic surfaces [30][31][32]. The surface modification with an APPJ has been applied to different applications.…”

Universal Plasma Jet for Droplet Manipulation on a PDMS Surface towards Wall-Less Scaffolds

Droplet manipulation is important in the fields of engineering, biology, chemistry, and medicine. Many techniques, such as electrowetting and magnetic actuation, have been developed for droplet manipulation. However, the fabrication of the manipulation platform often takes a long time and requires well-trained skills. Here we proposed a novel method that can directly generate and manipulate droplets on a polymeric surface using a universal plasma jet. One of its greatest advantages is that the jet can tremendously reduce the time for the platform fabrication while it can still perform stable droplet manipulation with controllable droplet size and motion. There are two steps for the proposed method. First, the universal plasma jet is set in plasma mode for modifying the manipulation path for droplets. Second, the jet is switched to air-jet mode for droplet generation and manipulation. The jetted air separates and pushes droplets along the plasma-treated path for droplet generation and manipulation. According to the experimental results, the size of the droplet can be controlled by the treatment time in the first step, i.e., a shorter treatment time of plasma results in a smaller size of the droplet, and vice versa. The largest and the smallest sizes of the generated droplets in the results are about 6 L and 0.1 L, respectively. Infrared spectra of absorption on the PDMS surfaces with and without the plasma treatment are investigated by Fourier-transform infrared spectroscopy. Tests of generating and mixing two droplets on a PDMS surface are successfully achieved. The aging effect of plasma treatment for the proposed method is also discussed. The proposed method provides a simple, fast, and low-cost way to generate and manipulate droplets on a polymeric surface. The method is expected to be applied to droplet-based cell culture by manipulating droplets encapsulating living cells and towards wall-less scaffolds on a polymeric surface.

“…[4][5][6][7][8][9][10][11] Others have deposited copper from various sources but used a high-power radiofrequency (RF) discharge. [12][13][14] Dey et al [15] used an ambient pressure dielectric barrier discharge (DBD) jet with copper oxide nanoparticles as a copper source. We previously reported that ambient air low-temperature (<40°C) PECVD of polymer films can be achieved by using a floating-electrode helium dielectric barrier discharge jet (He DBD jet).…”

This study demonstrates that plasma-enhanced chemical vapor deposition of copper films can be achieved in ambient air and at low temperature. A helium dielectric barrier discharge jet with a small mixture of hydrogen and copper(II) acetylacetonate vapor is utilized as the nonthermal plasma source to deposit conductive copper films with low electrical resistivity (<1 × 10 −7 Ω•m). The deposited film appears to have three distinct regions (reddish brown, dark blue, and yellowish) from center to edge. Copper nanograins (~50 nm) are observed in both the reddish-brown and the dark-blue regions, whereas the yellowish region exhibits a continuous structure containing copper oxide. The copper films are further deposited on various temperature-sensitive substrates, including plastic, cardboard, agar, and pork skin.
