Trimethylchlorosilane (TMCS) and ethyl alcohol were used as a surface treating agent and a solvent, respectively. Morphology, pore size distribution, specific surface area, chemical bonds, and hydrophobicity of the self-assembled particles were analyzed. The self-assembled particles were spherical in shape and composed of micro, meso and macro pores. Average diameter of the product particles was around 2 µm. The pore size distribution of the particles ranged from 1.5 to 200 nm. The degree of methanol wettability representing hydrophobicity of the product particles was directly proportional to TMCS concentration and ranged from 35 to 58%.","PeriodicalId":254587,"journal":{"name":"10th IEEE International Conference on Nanotechnology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115798407","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 sorting mechanism is based on antigen-antibody interaction and the secondary flow induced by oblique micro grooves on the channel surface. Specific adhesion between the cell membrane and the wall surface keep the target cells rolling on the wall, while the lateral flow along the groove induces cross-flow displacement of the target cell. Successful separation of cell models and human umbilical-vein endothelial cells (HUVEC) fully supports the proposed mechanism.","PeriodicalId":254587,"journal":{"name":"10th IEEE International Conference on Nanotechnology","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130477400","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}

Our technique is stripping graphene by scotch tape from the chemical vapor deposition (CVD)-grown layer, except the gap region between the source and drain electrode. The current-voltage (I–V) characteristic of a graphene FET before stripping shows a large zero-bias conductance of 6.5 mS and no gate operation. After stripping, the zero gate bias conductance of the device is reduced to 23 µS and a clear gate operation is observed. The change of FET characteristics before and after stripping is due to the formation of a urn size graphene flake. There is large potential that this one-step stripping technique can be extended to a more controllable method to fabricate graphene FET devices.","PeriodicalId":254587,"journal":{"name":"10th IEEE International Conference on Nanotechnology","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134038595","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}

Seldom documents report that it can transfer nano-objects in 3D space with high controllable precision. In this paper, we demonstrate that using developed AFM based nanorobot, viruses can be manipulated not only in 2D surface, but in 3D space. The experimental results show that a single virus can be picked up at a time and released to another special location by nanorobot. The theoretical analysis is presented to reveal the mechanism of a single virus' picking and releasing. A pyramidal structure is constructed with viruses to demonstrate the 3D manipulation capability of nanorobot.","PeriodicalId":254587,"journal":{"name":"10th IEEE International Conference on Nanotechnology","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130883546","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}

In this study, we propose and develop aptamer microarray platform combined with novel sol-gel technology to identify low abundance targets from complex solution, such as serum. Due to nanoporous structure of sol-gel, it entraps a large number of active aptamers and allows aptamers to bind target molecules with high sensitivity. TBP (TATA Box Protein) and their specific aptamers (aptamer #12 and #24) were chosen for a model system to a proof of concept. Broad ranges of sensing capability (from few nM to mM) with good linearity up to 400 nM were shown in our aptamer microarray platform by sandwich assay. Moreover, TBP protein can be identified by ESI/MS, electrospray mass spectrometry on the platform.","PeriodicalId":254587,"journal":{"name":"10th IEEE International Conference on Nanotechnology","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130910867","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}
