  1. Nanocomposite-Modified Electrodes for Sensing Biological Analytes

    30 Jul 2008 | | Contributor(s):: V. Yegnaraman

    Electrochemical sensing of analytes is mostly enabled by transducers based on potentiometry and amperometry. In this, design of sensing (working) electrode is of utmost importance since it only decides the sensitivity and selectivity features of the sensor. Chemical modification of the electrode...

  2. MCW07 Silicon Based Nanopore Sensors for Detection of DNA Molecules

    11 Sep 2007 | | Contributor(s):: Samir Iqbal, Demir Akin, Rashid Bashir

    Solid-state nanopores have emerged as possible candidates for next-generation DNA sequencing devices. In this talk, we will review our recent work in development of solid-state nanopore channels that are selective towards single strand DNA (ssDNA). Nanopores functionalized with a 'probe' of...

  3. On the Cross Roads of Biology and Nanotechnology – Selective DNA Nanopore Sensors

    21 Mar 2007 | | Contributor(s):: Samir Iqbal

    The ability to manipulate and identify the properties of singlebiological molecules with the potential of characterizing biologicalprocesses at the most fundamental levels can significantly facilitaterapid diagnostics and therapeutics. Fabrication of solid-statedevices investigating bacteria,...

  4. Vertically Aligned Carbon Nanotube for Interconnects and Nanoelectrode Based Biosensors

    15 Apr 2004 | | Contributor(s)::

    In the past few years, tremendous progress in the growth of carbon nanotubes (CNTs) has been made, which enabled the fabrication of various CNT devices for applications in electronics, biomedical techniques, and chemical/biological sensors. We have established a process to grow vertically...
