摘要： A novel bionanosensor (BNS) with multi-walled carbon nanotubes for the precise detection of DNA-hybridization was developed earlier using intermediate frequency electrical measurements. In the earlier project also a modeling technique for detailed understanding of the DNA-hybridization taking place on the surface of a sensor was also developed. In the current project, the authors have advanced the BNS fabrication using buckypaper for highly efficient detection of DNA-hybridization with controlled device resistance. Buckypaper is a thin sheet of an aggregate of carbon nanotubes (CNTs). Furthermore, the modeling of these sensors using pole-zero plots in the z -plane suggests the orientation of CNTs within the buckypaper in the presence of hybridized-DNA in the high frequency range (12–16 MHz). This modeling technique is not limited only to the BNS under study but significantly increases our knowledge on CNT–DNA interaction. Thus, this research yields successful application of buckypaper as a BNSs and strongly suggests the possible orientation of CNTs within buckypaper using hybridized-DNA at a high frequency range. 其他題名： J Nanopart Res 出版者： Dordrecht: Springer Netherlands 出版日期： 2013-04-01 出處： Journal of nanoparticle research : an interdisciplinary forum for nanoscale science and technology, 2013-04, Vol.15 (4), p.1, Article 1503 版權： Springer Science+Business Media Dordrecht 2013 版權： 2014 INIST-CNRS 識別號： ISSN: 1388-0764 識別號： EISSN: 1572-896X 識別號： DOI: 10.1007/s11051-013-1503-y
