However, efficient utilization as SERS substrates has been impeded by the difficulty of tuning SERS enhancement effects induced from chemical and plasmonic enhancement by different preparation methods of graphene. Herein, three kinds of graphene-based Au hybrid, CVD-G/Au, GO/Au and rGO/Au, which were synthesized by physical sputtering and chemical in-situ crystallization growth methods, were fabricated to evaluate as SERS substrates. Simple methods were developed to enhance the Raman signals effectively by tuning both plasmonic and chemical enhancement, respectively. Besides, the prepared rGO/Au nanocomposites were used as SERS substrates to monitor the process of plasmon-driven surface-catalyzed reaction from 4-nitrobenzenethiol (4-NBT) to p,p'-dimercaptoazobenzene (DMAB). According to systematic comparisons during power- and time-dependent SERS experiments, rGO/Au was demonstrated to be with lower power threshold and higher catalytic efficiency than Au nanoparticles (NPs) toward the reaction, which provide clues to understand the interaction between metal and graphene as well as further study of plasmon-driven chemical reactions for further.","PeriodicalId":6646,"journal":{"name":"2016 IEEE 16th International Conference on Nanotechnology (IEEE-NANO)","volume":"89 1","pages":"612-615"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77622543","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}

Despite similar zinc oxide concentrations, the colloids containing gold nanoparticles displayed stronger intensity dependent nonlinear absorption with optical limiting thresholds for the three samples of 35 J/cm2, 6.1 J/cm2 and 4.1 J/cm2, respectively.

Single cell isolation and characterization studies are crucial for unlocking the complex regulation pathways underlying various diseases like cancer. However, to date single cell isolation still faces many challenges, especially in processing rare samples. Here, we present a novel microfluidic array chip for single cell isolation for rare samples. Our design exempts the use of long tubing, thus decreases cell loss from dead volume and allows for more accurate control of flow rate using syringe pumps during the cell capture process. Our data showed that the device significantly improved single cell capture efficiency (~ 60 %) from small numbers of (50-500) cells in a small volume (5-10 μL). The device could be used for isolating single cells from rare samples of clinical specimens, thus potentially benefit disease diagnosis and therapy.","PeriodicalId":6646,"journal":{"name":"2016 IEEE 16th International Conference on Nanotechnology (IEEE-NANO)","volume":"15 1","pages":"222-223"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85724639","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 motion of the particle caused by thermal fluctuation is restricted within a narrow region because of gravity, and the vertical displacement of the particle from the bottom of the droplet depends on its mass. Since the particle is trapped inside the droplet, the mean horizontal displacement decreases as the mass of the particle increases. Hence, the mass can be determined by observing displacement. Although a modeling error arises from neglecting the electrical double-layer interaction between a particle and water surface, we show that its influence on the mass is very small.","PeriodicalId":6646,"journal":{"name":"2016 IEEE 16th International Conference on Nanotechnology (IEEE-NANO)","volume":"86 1","pages":"214-217"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85875110","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}

Transmittance values are similar in both fabrication techniques; however, the sheet resistance of the inkjetted layers diverges significantly with respect to the reference spray-deposited thin film. To overcome this limitation, we show a relationship between the printing resolution and the sheet resistance. Furthermore, big differences between the two studied substrates are found in the electro-optical characteristics of CNT films.
