Geometry of Diffusion and the Performance Limits of Nanobiosensors

05 Dec 2006 | Online Presentations | Contributor(s): Muhammad A. Alam, Pradeep R. 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 …

Nanoparticle Synthesis and Assembly for Biological Sensing

25 Oct 2005 | Online Presentations | Contributor(s): Gil Lee

Nanoparticles have unique physical and chemical properties that make them very useful for biological and chemical sensing. For example, colloidal gold has been used as an optical transducer for antibody based sensing for over twenty years and is the basis for a many of the point-of-use …

Nanosystems Biology

09 Sep 2004 | Online Presentations | Contributor(s): James R. Heath

As we enter the 21st century, we stand at a major inflection point for biology and medicine-the way we view and practice these disciplines is changing profoundly. These changes are being driven by systems biology, a new approach to biology, and which will increasingly transform medicine from …

An Introduction to BioMEMS and Bionanotechnology

25 May 2005 | Courses | Contributor(s): Rashid Bashir

This lecture series introduces the basic concepts and key topics underlying the interdisciplinary areas of BioMEMS and Bionanotechnology. Advances in this field require the knowledge of polymer processing and soft lithography in addition to knowledge of silicon-inspired fabrication. Since the end …

Engineering Nanomedical Systems

16 Nov 2007 | Online Presentations | Contributor(s): James Leary

This tutorial will cover general problems and approaches to the design of engineered nanomedical systems. An example to be covered is the engineering design of programmable multilayered nanoparticles (PMNP) to control a multi-sequence process of targeting to rare cells in-vivo, re-targeting to …

Quantum Chemistry Part II

22 Nov 2005 | Online Presentations | Contributor(s): George C. Schatz

This tutorial will provide an overview of electronic structure calculations from a chemist's perspective. This will include a review of the basic electronic structure theories.

Practical Introduction to the BioMOCA Suite

23 Apr 2008 | Online Presentations | Contributor(s): David Papke

In this presentation, I describe how to use the online BioMOCA Suite. I explain how to prepare the .pqr input protein structure from a .pdb structure. I then explain in detail how to use each of the four subtools in the BioMOCA Suite. I do not cover in detail how the BioMOCA code works. If you …

This tutorial will provide an overview of electronic structure calculations from a chemist's perspective. This will include a review of the basic electronic structure theories.

DNA Charge Motion: Regimes and Behaviors

01 Sep 2005 | Online Presentations | Contributor(s): Mark A. Ratner

Because DNA is a quasi-one-dimensional species, and because each base is a pi-type chromphore, it was long ago suggested that DNA could conduct electricity. This has become a widely investigated area, and remains of interest for fundamental science and for applications. We will discuss a very …
