MWCNTs were grown on a TiN coated quartz plate with Fe catalysts patterned by UV nano-imprint lithography (NIL)1. The proposed study is the realization of a simple, inexpensive and reproducible method to produce nanoscale electrode arrays in large areas. The patterns were defined by an array of circles 200 nm in diameter, and 500 nm in pitch. The nano-patterned master and Fe catalyst are observed with good pattern fidelity over a large area by atomic force microscope (AFM) and scanning electron microscopy (SEM). Among various synthesis methods for carbon nanotube growth, plasma-enhanced chemical vapor deposition (PECVD)2 was used for the growth of vertically aligned multi-wall carbon nanotube arrays. Ammonia (NH3) and acetylene (C2H2) were used as the etchant gases and the carbon source, respectively. The carbon nanotubes were vertically aligned in high density on a large area of the plain quartz substrates. High-resolution transmission electron microscopy (TEM) analysis reveals that the synthesized CNTs have multi-walls and bamboo-like structures. Patterned catalysts made it possible to allow the precise placement of individual CNT electrodes on the substrate. These electrodes have diameters ranging from 50 nm to 100 nm and lengths of about 300 nm. A field emission test using isolated CNTs on quartz plates showed the ability of CNTs as nano-electrodes. Bio compatibility was also investigated by cell culturing on the fabricated CNTs/quartz template for potential bio-applications.","PeriodicalId":424336,"journal":{"name":"2016 IEEE International Conference on Plasma Science (ICOPS)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134358922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Medical applications of atmospheric-pressure plasmas (APP s) in ambient air at room temperature have been widely studied because of APPs' ability to provide reactive oxygen / nitro gen species (RONS) to living tissues. Although the effectiveness of plasma-based therapies for some types of medical treatments has been widely reported, it has not been clear yet how such plasmas interact with living cells and tissues and what specific chemical spices contribute to the observed therapeutic effects. In an attempt to address such questions, we have performed numerical simulations of chemical reactions and transport of reactive species in liquid exposed to a low-temperature APP. The governing equations that we have employed for this study are reaction-diffusion-advection equations coupled with Poisson equation. For the sake of simplicity, we only consider pure water as the solvent. The rate constants, mobilities, and diffusion coefficients are obtained from the literature. The gaseous species are given as boundary conditions and time evolution of the concentrations of these chemical species in pure water is solved numerically as functions of the depth in o ne dimension. In addition to the case where the water surface is irradiated by a plasma, we have also experimentally examined the case where a plasma is generated in water by nano-second high voltage discharges. The results of both numerical simulations and discharge experiments will be presented.","PeriodicalId":424336,"journal":{"name":"2016 IEEE International Conference on Plasma Science (ICOPS)","volume":"422 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133718252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different gas plasma can be used for creating specific surface chemical bonds on material surfaces. These bonds can then be utilized for detection of different chemicals and biomolecules. Biosensors are currently being used for a variety of sensing ranging from medical diagnosis, drug development, food industry and environmental monitoring. The bio analyte is detected by the interaction with the biological element like protein, DNA, peptide, etc. on the surface of the sensor and the signal is transmitted as a electrical, mechanical or optical one. There is a growing demand to develop biosensing surfaces that can be easily integrated with electronics to make highly efficient analytical devices.Here we present our research on developing a biosensor platform using functionalized silicon nitride (SiNx) films. SiNx is chemically inert and easily integrated with other solid state devices and thus is an attractive material for biosensing. We utilize inductively coupled (ICP) reactive ion etcher (RIE) for plasma activation of the SiNx films. The films are functionalized using hydrogen plasma in an ICP-RIE which permits use of low power plasma to reduce the surface damage and increase the efficiency of activation. We have demonstrated high number of amine bonds on the surface in the range of 5 x 1012 /cm2. This was measured by attaching m-Cherry protein to the surface using a light activated crosslinker. Due to the high surface activation efficiency a small area sensor can be developed with high sensitivity. Different proteins can be attached for sensing different biomolecules. Results from this research will be presented.","PeriodicalId":424336,"journal":{"name":"2016 IEEE International Conference on Plasma Science (ICOPS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132935422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Candida albicans cell wall is composed of mannoprotein, β-Glucan and chitin. To explore the antitumor activity of components produced by Candida albicans, nanoelectropulse was introduced in t his study. Candida albicans viability after nanoelectropulse exposure were assessed by colony-forming unit (CFU) assay and fluorescence microscope. Morphological changes of Can dida albicans were observed by scanning electron microscopy (SEM). Also, the total nitric oxide concentration after nanoelectropulse exposure were estimated by the total nitric oxide assay Kit. Finally, the antitumor activity of Candida albicans components were investigated by CCK-8 assay and Annexin V-FITC/PI apoptosis assay in Hela and Cal-27 cancer cell line s. Results suggested that there is a window effect of nanoelectropulse on Candida albicans. High field strength (40kV/cm, 100 pulses) of nanoelectropulse has an electropermeabilizatio n effect on Candida albicans. Additionally, Candida albicans components isolated from 40kV/cm, 100 pulses exhibited good antitumor activity against Hela and Cal-27 cancer cell line s. More importantly, our results revealed that nanoectropulse can significantly affects the Candida albicans to get β-Glucan and Nitric Oxide. Undoubtedly, β-Glucan and Nitric Oxide play an important role in anticancer activity. This is a proof-of-concept study, and provides the first evidence of the nanoectropulse might take Candida albicans for further potential deve lopment as a valuable therapeutic option for cancer patients.","PeriodicalId":424336,"journal":{"name":"2016 IEEE International Conference on Plasma Science (ICOPS)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131901903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Development of a switch capable of operation at high voltages, high repetition frequency, with long lifetime is essential for furthering pulsed power applications. Photoconductive semiconductor switches (PCSSs) possess inherent optical isolation and extremely low switching jitter (~10 ps), and have also been experimentally shown to be capable of switching high voltages (up to 50 kV) and currents with very fast rise and fall times (<; 1 ns)[1-2]. In this paper, we report the breakdown characteristics of a SiC PCSS triggered spark gap obtained via measurement of the voltage and current, and simulation of the electric field distribution. The triggered spark gap is composed of sphere-to-sphere electrodes and a field distortion electrode, which is kept at mid-potential in the center plane between the two spherical main electrodes. A normally open PCSS is connected between one of the main electrodes and the mid-plane (trigger) electrode, whose center bore diameter is varied from 5 to 15 mm. With application of the optical pulse to the PCSS, the trigger electrode is temporarily connected to the main electrode, effectively doubling the electric field between the trigger and opposite electrode, leading to main gap closure. In essence, while bulk SiC PCSS switching currents demand very high optical power input, the synergy of bulk SiC PCSS and traditional spark gaps enables the triggering of large current flows at very modest optical powers with low jitter. Overall, the obtained results reveal that incident laser energy and mid-plane electrode geometry heavily influence the breakdown characteristics of the spark gap including jitter time, and breakdown voltage.","PeriodicalId":424336,"journal":{"name":"2016 IEEE International Conference on Plasma Science (ICOPS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116922664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
