Thank You. </h3> <div> <h2>Gold Nanorods</h2><br><p style="line-height:200%; font-family: Century Gothic, sans-serif, Impact, Charcoal; font-size:145%"> Gold nanorods are a specific class of metallic nanoparticle created by anisotropically growing spherical gold nanoparticles. These nanorods are approximately 80nm long, and 20nm wide. They are functionalized with citrate, which stabilizes them in solution. Gold nanorods are unique due to their unique optical and electronic properties. These properties are the result of surface plasmon resonances created by the oscillations of conduction band electrons in subwavelength metallic nanostructures. These surface plasmon resonances are particularly interesting in that two separate plasmon bands emerge when looking at the absorbance spectra of gold nanorods: one for the shorter, transverse axis of the rods, and one for the longer, longitudinal axis. </p> </div> <div> <p id="edutext"> <h2>Quantum Dots</h2><br>Quantum dots are a category of semiconducting nanoparticle with highly tunable optical and electronic properties. The unique properties of the quantum dots are due to their diameter being smaller than the Bohr radius. The Bohr radius is the distance at which electrons orbit a nucleus. At sizes this small, the electrons of the particle are said to be “confined”, resulting in a highly sensitive bandgap which can be tuned precisely by varying particle size. </p> </div> <div> <p id="edutext"> <h2>Electrospinning</h2><br>In order to accomplish the macroscale alignment of our heterodimers, we deposited them into polymer fibers through the process of electrospinning. For electrospinning, the heterodimers are first suspended in polyethylene oxide.The polymer solution is then slowly extruded from a syringe as a voltage is applied. This voltage causes the solution to jet across a gap and deposit onto a collector positioned a short distance away. While in the air, the solvent from the solution evaporated, leaving only the thin polymer fibers to deposit onto the collector as a mat. A schematic of such a setup is shown in figure 1. Our heterodimers are imbedded within these polymers, aligned along the fiber centers. Previous work has shown it is possible to electrospin gold and quantum dot nanorods/nanoparticles successfully using such a method, as illustrated in figures 2 and 3.</p> <p> </div> <div style="float:LEFT;margin:5 20px 5px 5;"> <img src="http://i.imgur.com/TnhOn8H.jpg" width="420" > </div> Figure 1 -- Garth, W.
