The discrete devices included a pair of W/Au opposed electrodes and SWNT bundles that were assembled between electrodes by DEP. We used Al lines to connect the two electrodes of all devices to two large Al pads. AC DEP bias were applied on Al pads and the SWNTs were self-assembled at the same time. Then Al was etched so that W/Au electrodes of the same polarity were disconnected and all devices were discrete electrically. The density of SWNT devices was 3 times larger than before. The electrical measurement showed that ohmic contact was formed between the assembled SWNTs and the electrodes. Our sacrificial electrode DEP method made it more flexible to achieve SWNT devices in large scale.","PeriodicalId":22566,"journal":{"name":"The 9th IEEE International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"81 1","pages":"582-585"},"PeriodicalIF":0.0,"publicationDate":"2014-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74973716","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}

Thus extending the concept of quantum mechanics into design of new electronic devices becomes more important. Controlling the movement of these electrons plays the central role in this issue. In this work, we propose a new quantum cloaking mechanism which has completely different to the previous work of Liao et al [1]. This mechanism is based on the scattering cancellation and the interplay among the nodal points of partial waves, that one can simultaneously guide the probability flux outside the interior and keep the total scattering cross section negligible. Moreover, we can put any electric devices inside quantum cloaking without affecting outside probability of matter wave. With the analogy between quantum matter waves and classical waves, the concept of our method can be applied in other fields, such as electromagnetic and acoustic systems, etc.","PeriodicalId":22566,"journal":{"name":"The 9th IEEE International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"38 1","pages":"386-389"},"PeriodicalIF":0.0,"publicationDate":"2014-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86181830","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}

Measurement of protein by a semiconductor may encounter a major problem. For specifically measuring protein, an antibody is immobilized on the semiconductor sensor surface. The physical length of the antibody is around 10 nm, a distance too long to be sensed by the semiconductor sensor, which means that the following attached protein cannot be sensed. In this study, we used a bead-based immunoassay combined with the DNA strain labeling technique to overcome this issue. Protein was first captured using an antibody-coated magnetic bead. It was then labeled with a secondary antibody combined with the DNA strain. Finally, the magnetic bead with the biotarget was attracted on the sensor surface by an external magnetic field, and then the negative charges of the DNA changed the surface potential of the sensor. The concentration of protein could then be measured accordingly. The signal could be further improved by the optimization of the number of labeling DNA and the size of the magnetic bead. In addition, the semiconductor sensor was incorporated in a microfluidic chip with microvalves and a micromixer. The microfluidic procedure reduced the total measurement time to around 1 h (plate ELISA 4h). Furthermore, by changing the antibody to another type of antibody coated on the magnetic bead, the sensor could be reused to measure other types of protein. The proposed method provides a solution for the robust measurement of protein concentration through the semiconductor sensor.","PeriodicalId":22566,"journal":{"name":"The 9th IEEE International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"21 1","pages":"329-332"},"PeriodicalIF":0.0,"publicationDate":"2014-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81606072","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}
