Traditional injection technology used piezo actuator to drive pipettes and a small mercury column was applied in micropipette to diminish the lateral tip oscillations. This injector significantly improves the survival rates of the ICSI process, but large lateral tip oscillations of the micropipette and the toxicity of mercury may damage to the cell membrane with a lower survival rate. Based on the theoretical basis of the previous generation injection structure and conventional injection system, a new design of the piezo-driven microinjector is proposed for microinjection. In this paper, the new structure uses packaged piezo actuator as driving source for connecting more stable and reliable. And it adopts two points flexible way to fix the pipette instead of the way of one point. The design parameters have been optimized for meeting the requirements of small cell injection. It's more simple and easy to use. This paper used simulation software to study the lateral vibration of the new structure, and optimized design size for minimum the lateral oscillation of micropipettes. Harmful lateral tip oscillations of micropipette are reduced substantially during simulation. Finally, we make the new microinjector by 3D printing technology for future experiment. This new structure will reduce the damage to cells in a large extent with a high success rate.","PeriodicalId":367660,"journal":{"name":"14th IEEE International Conference on Nanotechnology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130269193","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 latter is limited by the etching rate selectivity between the resist and the substrate material, which is usually on the order of unity for dry plasma etching. Moreover, some metals including most noble metals cannot be dry etched. Thus liftoff is often the preferred pattern transfer method. Liftoff is typically carried out using a solvent that dissolves the resist. A strong solvent aided by ultrasonic agitation and/or heating is sometimes needed if the resist is difficult to dissolve due to, for example, cross-linking by exposure to electron beam or plasma. Another serious issue with conventional liftoff process is that the metal debris may stay at the active device area after drying. To avoid the above issues, dry liftoff using mechanical approach may be utilized. Here we report a simple dry liftoff technique using a scotch tape to peel off the resist film coated with the material to lift off. We obtained high resolution (down to 50 nm) liftoff of metal and organic materials polystyrene and Alq3, with PMMA as electron beam resist coated on a substrate treated with a low energy surfactant.","PeriodicalId":367660,"journal":{"name":"14th IEEE International Conference on Nanotechnology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127584424","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}

These systems are named as mixed-carbon-filler filled systems (MCFFS). The electrical conductivity was measured by the four point probe and the dispersion was analyzed by High Resolution Transmission Electron Microscopy (HR-TEM). It has been shown that the addition of MWCNT and CB in PMMA promoted the electrical conductivity of the composite as a percolation critical concentration is reached. The percolation threshold values were 0.2 vol. (%) for MWCNT and 1.5 vol. (%) for CB, showing that this difference for the two fillers was associated with their geometric shapes, aspect ratios and dispersion characteristics. In addition, MCFFS of MWCNT and CB, varying the concentration of each filler were also prepared. For these systems it was applied the Sun model in order to calculate the theoretical values and compare them to the experimental data. It was observed the synergic effect regarding to the electrical percolation threshold concentration. The MCFFS showed lower critical concentrations (considering the sum of each single filler concentration, MWCNT and CB) and similar conductivities as compared to the single fillers. Despite the presence of aggregates, the microscopy analysis showed that both fillers were well dispersed in the polymer matrix, although the dispersion characteristics of the MWCNT were more effective than CB. In the MCFFS the MWCNT act as filaments linking clusters of the CB, what can explain the synergic effect observed for the lower percolation threshold concentration.","PeriodicalId":367660,"journal":{"name":"14th IEEE International Conference on Nanotechnology","volume":"261 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133153225","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}
