Furthermore, advances in engineering, control and automation on the nano scale first enable so far impossible studies in molecular and cellular biology. This fruitful interaction leads to the design and development of new setups and methods, which push the boundaries for possible experiments in the area of handling and manipulation of biomaterials. In our paper the latest work on two areas of this research focus is shown. 1) Within the last years, the AFM was used for the handling and manipulation of biomaterials. However, the automation to use the AFM for industrial processes needs a robust and accurate automation. In this paper we also present the latest work on the automation of AFM based methods. 2) In the future, mobile diagnostics will become more and more important. To enable robust, fast and precise systems, new methods for the design and structuring of the necessary bio-components are needed. For this, a possible approach to structure bio-components from several nm up to a few μm is presented in this paper as well. 3) First simulations and principles for the design of a new signal acquisition unit are shown, to set up diagnostic systems without complex optical setups or fluorescence dyes.","PeriodicalId":159995,"journal":{"name":"2012 IEEE Nanotechnology Materials and Devices Conference (NMDC2012)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131223067","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}

GO is an insulator because of the hydroxyl, carboxyl, carbonyl and epoxide functional groups presenting on the basal surface or edge and becomes a semiconductor or semimetal as it is reduced back toward graphene. Here we demonstrate that graphene oxide can be reversibly reduced and oxidized in nanometer-scale by applying bias voltages by the nano-tip of conductive atomic force microscopy system. The low resistance state (LRS) when reduced and a high resistance state (HRS) when oxidized can be achieved under the opposite applied bias direction. The LRS (around 10 KΩ and HRS (around 40 M Ω) were stable for more than 103 s, and no obvious degradation was observed during the tests. Threshold voltages for reduction and oxidation, which can be considered as the set and reset voltages is around -6.5 V and +7 V, respectively. It is shown that the hydrogen (H+) ions and hydroxyl ions (OH-) dissociated from the water meniscus formed between the tip and GO in ambient condition at room temperature plays an essential role in the resistive memory switching. It is also found that the negative bias is responsible for the reduction, which is related the transition from HRS to LRS, and the positive bias is responsible for the oxidation, which is related the transition from LRS to HRS, respectively. Raman spectroscopy and X-ray photoelectron spectroscopy is performed to confirm this resistive memory switching behaviors.","PeriodicalId":159995,"journal":{"name":"2012 IEEE Nanotechnology Materials and Devices Conference (NMDC2012)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121201485","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 fabrication of optimized emitters that can allow the low recombination below the silver front contact is an important process in solar cell fabrication. This selective emitter approach presents a heavily doped layer beneath the electrode and lightly doped regions between the electrode grids. Selective opening of the anti reflection coating is needed to implement this combination of heavily and lightly doped regions. This was achieved using an inkjet approach by printing an etchant-dopant ink followed by the printing of a diffusion barrier using a dielectric ink. Using a Trident Jet256S industrial printhead we created etched pattern with etch width -50 μm. Once this pattern was created, the metallic front contact grid was printed using a silver nano-ink on top of the etched regions. Inkjet printed silver front contact grid with line width -75 μm was printed successfully.","PeriodicalId":159995,"journal":{"name":"2012 IEEE Nanotechnology Materials and Devices Conference (NMDC2012)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114608039","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}

A Theologically tailored conductive silver nano-ink was created to meet the rheological requirement of industrial printheads (XAAR 1001). The jetting optimization for the printhead was done using a desktop R&D inkjet printer from PiXDRO (OTB Solar). Printer-integrated software allowed the optimization of droplet formation and droplet stability during the jetting process. Typical printing parameters such as greyscale, DPI variation, substrate heating, etc., were optimized to achieve high print quality. However, initial printing results showed poor line definition and inhomogeneous film thickness. To overcome this, we developed a multiple pass printing process that results in excellent line definition. We also performed statistical analysis to correlate the droplet size with printed feature size. The minimum feature size of -15 μm was achieved by jetting ~6 pi droplets. After printing, the films were sintered thermally to achieve metallization. Detailed TGA study showed that complete metallization was achieved at temperature 400°C. Adhesion tests performed using an ASTM standard tape test on printed pattern showed less than 5% of delamination or flaking. Finally, test prototypes of solar front electrodes were printed successfully on ITO and silicon substrates.","PeriodicalId":159995,"journal":{"name":"2012 IEEE Nanotechnology Materials and Devices Conference (NMDC2012)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132093745","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}
