  9. 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...

  10. Micro-scaled Biochips with Optically Active Surfaces for Near and Far-field Analysis of Cellular Fluorescence

    The integration of thin (< 100 nm) metal films with micro-scaleoptical waveguides provides a route to controlled spatialexcitation of cellular fluorescence within a biochip platform.Surface bound electron-plasma oscillations (surface plasmon waves)interact with photons to produce an...

  11. Oligodeoxyribonucleotide Association with Single-Walled Carbon Nanotubes

    02 Aug 2007 | | Contributor(s):: Jennifer McDonald

    Commercially available single-walled carbon nanotubes (SWCNTs) tend to aggregate as ropes and bundles during production making them of little use in many scientific and industrial applications. An effective technique for dispersing and solubilizing SWCNTs is required to fully utilize their...

  12. Re-engineering a Healthy Eye Tissue to Restore Damaged Eyesight

    02 Aug 2007 | | Contributor(s):: Margarita Shalaev

    Age-related macular degeneration (AMD) is an eye disease that is the leading cause of blindness in the USA and Western Europe. It affects over one million people in the United States alone. One of the symptoms of AMD is a diseased Bruch’s membrane, which is an important layer in the eye. Our...

  13. Biosensing applications of Plasmon Resonance in gold nanoparticles

    02 Aug 2007 | | Contributor(s):: Karina Moore

    Light can be used to excite plasmon resonance in gold nanoparticles. Plasmon resonance occurs on the nanoscale as the particles become excited and plasmon oscillations arise in each particle of a pair of metal nanoparticles. There is plasmon coupling between the neighboring particles as the...
