The characteristic individual magnetic behavior, as well as the metal-to-metal charge-transfer capabilities of the various samples, could be related to significant changes within the structure that appear to be associated with the synthesis method used.","PeriodicalId":254587,"journal":{"name":"10th IEEE International Conference on Nanotechnology","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124949060","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 SWNTs were dispersed in sodium dodecyl sulfate (SDS) and were applied over the electrodes of an interdigitated electrodes (DDEs) by photolithography. By using this method, the active area for gas sensing can be defined more clearly than with simple dropping or stamping, though it is still difficult to control the concentration of dispersed composite. Our sensor showed faster response to the CO gas than the NH3 gas. The CO increased the conductance of the composite, while NH3 showed an opposite response. Nevertheless, the composite were more adsorptive to CO than NH3. In addition, we observed CO and NH3 gases were mixed carefully with the same concentrations of 5 ppm.","PeriodicalId":254587,"journal":{"name":"10th IEEE International Conference on Nanotechnology","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116971679","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}

Recently, electroactive polymers are said to be promising materials as advanced soft actuators. Its mechanical motion is controlled by external stimuli such as a change in solvent composition, pH, temperature and electric field etc. On the other hand, many living organisms generate an autonomous motion without external driving stimuli. In this proceeding, we report a novel biomimetic gel actuator that can generate peristaltic motion spontaneously without external driving stimuli. The gel actuator converts the chemical energy of oscillating reaction, i.e., the Belouzov-Zhabotinsky (BZ) reaction into the kinetic energy inside the gel. Although the gel is completely composed of synthetic polymer, it shows autonomous motion as if it is alive. We consider that this gel actuator will create a new framework of chemical robot.","PeriodicalId":254587,"journal":{"name":"10th IEEE International Conference on Nanotechnology","volume":"182 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134228915","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 these experiments, the detection of Biotin/Streptavidin binding is of special interest since the biotin/ Streptavidin system exhibits the strongest noncovalent biological interaction known and is widely demonstrated as a model system to study biorecognition between proteins and other biomolecules. In this paper, a comprehensive modeling theory and simulation approach is presented to account for the underlying detection mechanism of biotin/Streptavidin binding using SiNW FET biosensor.

A 4 by 1 array of the spheroid chips has been designed, fabricated and characterized. The experimental study demonstrates that the spheroid chip is capable to form, culture, and extract the multicellular tumor spheroids having the diameter of 197.2α11.7µm with the cell viability of 80.3α7.7%.

By applying a femtosecond laser for the selective sintering of metal nanoparticles on a heat sensitive substrate, the heat-affected zone during the laser sintering process can be minimized.

To improve the resolution of e-beam patterning, we investigated the tendencies of some e-beam process parameters such as dose, beam current, shot pitch, writing method and development time as well on the glass substrate. The charging and backscattering effects were also analyzed with the thin metal film on top of the resist. Based on above experiment results, the minimum acceptable critical dimensions have been evaluated for variable metal thicknesses on top of the resist.
