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}

The z-scan technique was used to measure the nonlinear absorption of zinc oxide, zinc-oxide: gold hybrids and mixed colloids of zinc-oxide and gold. 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}

Among multiferroic materials, bismuth iron oxide (BiFeO3) is a promising candidate as it offers advantages of high antiferromagnetic Neel temperature and high ferroelectric Curie temperature. An alternate to the conventional sol-gel method is proposed in the form of microwave exposure is proposed for the synthesis of nanoparticles. We here report structural, magnetic and dielectric properties of lanthanum doped bismuth iron oxide (Bi1-xLaxFeO3) nanoparticles with dopant concentration x as 0.3. Microwave power is varied as 180W, 450W and 810W. Microwave assisted nanoparticles are studied without any post treatment. Low microwave power results in amorphous nature of nanoparticles while transition to phase pure crystalline nanoparticles was observed at microwave power of 450W. High microwave power of 810W results in separation of bismuth deficient phase and BiFeO3 phase. Dielectric constant increases from 718 to 1095 as microwave power is increased from 180W to 450W. Transition from weak magnetic behavior to strong ferromagnetic behavior arises due to combined advantages of La doping and use of microwave power.","PeriodicalId":6646,"journal":{"name":"2016 IEEE 16th International Conference on Nanotechnology (IEEE-NANO)","volume":"164 1","pages":"994-997"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72950447","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}
