Biosensing applications of Plasmon Resonance in gold nanoparticles
02 Aug 2007 | Online Presentations | 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...
Introduction to Self-Assembled Monolayers and Biosensors
01 Aug 2007 | Online Presentations | Contributor(s): Michael Toole
Recent research concerning self-assembled monolayers (SAMs) focuses on tasks from fabrication of microelectronics to creating biosensors. This presentation will address the fundamental principles of self-assembled monolayers, formation and analysis of self-assembled monolayers, the basics of...
The Effect of Physical Geometry on the Frequency Response of Carbon Nanotube Field-Effect Transistors
03 Aug 2007 | Online Presentations | Contributor(s): Dave Lyzenga
In order for carbon nanotube (CNT) electrical devices to be fabricated, it is necessary to obtain modifiable operation characteristics. Developing parametric equations to achieve this controllability in the vertical field-effect transistor (FET) design is an important first step toward...
Re-engineering a Healthy Eye Tissue to Restore Damaged Eyesight
02 Aug 2007 | Online Presentations | 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...
Pulsed Laser Deposition of Thin Films
02 Aug 2007 | Online Presentations | Contributor(s): Josh Kaufman
Thin metal films have many applications from optical limiters to nanocircuits. Methods for fabricating these films differ in theory and complexity. Pulsed Laser Deposition (PLD) is a popular method for fabricating thin films. A number of thin films were fabricated using PLD. Silver films of...
Direct Microcontact Printing of Gold and Silver on Silicon
02 Aug 2007 | Online Presentations | Contributor(s): Jamie Nipple
Because microcontact printing (µCP) allows the fabrication of disposable electronic devices with minimum cost, this technique has proven useful in the patterned functionalization of certain chemicals onto surfaces. In time, µCP should allow for the fabrication of sub-10-nanometer structures and...
Oligodeoxyribonucleotide Association with Single-Walled Carbon Nanotubes
02 Aug 2007 | Online Presentations | 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...
Carbon Nanotube Mission
02 Aug 2007 | Online Presentations | Contributor(s): Adaku Ochia
Carbon nanotubes have become an interesting phenomenon over the past couple of years as electrical devices and electro-mechanical systems have dramatically shrunk in size. Accidentally discovered by Sumio Iijima while he examined carbon fullerenes, these needle like structures, he later named...
