On Modeling Metabolic Systems
04 Jan 2007 | | Contributor(s):: Doraiswami Ramkrishna
Modeling metabolism has been generally based on the numerouscellular reactions to be in steady state with respect to theexternal fluxes on the cell boundary. The essence of this"steady state" approach is the identification of all thereaction rates (fluxes), both external and internal to the...
Plasmon-resonant Nanorods as Multifunctional Imaging Agents
28 Dec 2006 | | Contributor(s):: Alexander Wei
Gold nanorods have several outstanding characteristics as optical contrastagents for biomedical imaging. Their strong optical absorption atnear-infrared (NIR) frequencies can be used to generate contrast for opticalcoherence tomography (OCT) imaging, and is well matched for detectionmodalities...

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...
