But contactless conductivity detection is restricted by its sensitivity, how to improve detection sensitivity has become the key of contactless conductivity. In this paper a novel extended model for the detection cell consisting of a network of resistors and capacitors is proposed according to the structure of contactless conductivity detection. The effect of the detector geometry on the sensitivity of contactless conductivity is studied. By simulation, the optimal parameters are obtained. Sandwich electrode structure was established to improve the performance of the detector and minimize the stray capacitance between the electrodes.

The electrodes were designed as symmetrical hyperbolic formatted to generate linearly decrescent electric field. Cells were cultured on the microchip for adherent electroporation and in-situ observation. Exhibited diversely in cell viability and transfection efficiency, three areas were observed obviously since the intensity of electric field was varied. Assisted by markers designed on electrodes, the location of optimal electroporation performance area and the corresponding range of electric field intensity were determined. Using the proposed electroporation chip, we obtained the optimal electric field spectrum for electroporation of HEK-293A cell line, that was about 0.75 ~ 1.25 × 105 V/m. The diversity of electroporation performance was evaluated by the dependence of cell viability and transfection efficiency on electric field intensity. With the guidance of reference electric field value, we designed a specific annular-interdigitated microchip to testify the electroporation characteristics. At last, we achieved excellent electroporation performance under the optimal conditions using self-made electroporation microchip.","PeriodicalId":308928,"journal":{"name":"The 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115505543","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 width of the channel is 0.8 mm in a μPHP having uniform channels, and 1.0 mm or 0.6 mm in the other μPHP. The depth of each channel is 0.25 mm. The overall size of each μPHP is 60 mm × 10 mm × 1.25 mm. Both visual observation and temperature response of the present μPHPs at various conditions were performed. The performance was compared between two μPHPs having either uniform channels or non-uniform channels at difference heating powers. Results showed that both μPHPs could not start the pulsating two-phase flow in the channel of μPHPs as the μPHPs were operated horizontally at heating power ranging from 1 W to 7 W, except when the μPHP having non-uniform channels was tested at heating power of 7 W. Unlike the failure start-up for horizontal arrangement of μPHPs, μPHPs with a vertical arrangement shows a significant start-up phenomenon for both μPHPs with uniform and non-uniform channels due to the assistance in the start-up of both μPHPs arising from gravity force.","PeriodicalId":308928,"journal":{"name":"The 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116055089","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}
