On the Cross Roads of Biology and Nanotechnology – Selective DNA Nanopore Sensors
out of 5 stars
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,...
SUGAR: the SPICE for MEMS
21 May 2007 | | Contributor(s):: Jason Clark
In this seminar, I present some design, modeling, and simulation features of a computer aided engineering tool for microelectromechanical systems (MEMS) called SUGAR. For experimental verification, I use a microdevice that is difficult to simulate with conventional MEMS software. I show that the...
Toward Improving the Precision of Nanoscale Force-Displacement Measurements
13 Mar 2007 | | Contributor(s):: Jason Clark
Nanotechnology has great potential for being used to create better medicines, materials, and sensors. With increasing interest in nanotechnology to improve the quality of our lives, there has been an increasing use of nanoscience tools to measure force and displacement to understand nanoscale...
Geometry of Diffusion and the Performance Limits of Nanobiosensors
05 Dec 2006 | | Contributor(s):: Muhammad A. Alam, Pradeep Ramachandran Nair
This presentation demonstrates how the classical diffusion-capture (D-C) model has improved sensor performance, since the D-C model is a "geometry of diffusion" rather than a "geometry of electrostatics." A scaling law based on D-C is also posited; the scaling law resolves many classical puzzles...
