  4. Fine Tuning Microcantilever Vibrations for Ultrasensitive Analyte Mass Detection

    27 Jul 2005 | | Contributor(s):: Arvind Raman

    Microcantilever based biochemical sensing has shown tremendous promise for ultrasenstive detection in both liquid and ambient conditions. However improving the sensitivity, reliability and robustness of these sensors so they can achieve their potential needs substantial efforts in (a) chemical...

  5. A Novel Diagnostic Assay Based On Nanomechanics

    28 Jul 2005 |

    Micro-fabricated silicon cantilevers arrays offer a novel label-free approach where ligand-receptor binding interactions occurring on the sensor generate nanomechanical signals like bending or a change in mass that is optically detected in-situ. We report the detection of multiple unlabelled...

  14. Bioinformatics and Systems Biology: At the Crossroads of Biology, Engineering, and Computation

    08 Oct 2004 |

    Traditional biological research has relied on a "deconstructive" mode where piece-wise analysis of the components of complex systems was carried out in detail. The genome projects have spurred the discovery of new genes/molecules to add to the existing inventory of "parts" that make up living...

  15. Interfacing Carbon Nanotubes with Biological Systems: From Biosensors to Cellular Transporters

    21 Oct 2004 |

    This talk will discuss two relatively new topics in carbon nanotube research.
