applications by studying the effects that ligands have on the optical properties of the nanocrystal. Ligands control the solubility and photoluminescence efficiency of the nanocrystals. The ligands present after synthesis, the native ligands, are what keep our nanocrystals in solution. We evaluate the effects of different ligands by monitoring the photoluminescence of the nanocrystal as we exchange the native ligands with other ligands such as pyridine. Nanocrystals can be synthesized into many shapes

cells. Characterization of the nanoparticles was performed using FT-IR, XRD, TEM and DLS, and cell targeting was observed using Prussian blue staining and MRI in mice. The modified nanoparticles were found to decrease cytotoxicity and macrophage cell capture and increase colloidal stability and hydrophilic properties in mice suggesting beneficial use in specific tumor targeting. 4:00 pm - Synthesis and Reactivity of 2-ethenyl-2-cyclohexenolEmily Tollefson, Senior Capstone Seminar It is proposed that

showed differences in soil communities due to height above ground, tree species and location of sampling site. 1:40 pm - Surface-Enhanced Raman Spectroscopy Using Colloidal Gold NanoparticlesChristopher Bingham, Senior Capstone Seminar Colloidal gold nanoparticles were synthesized and employed in SERS studies of several small molecules. Several synthetic methods were explored in an effort to optimize the SERS activity of the nanoparticles. Hydrogen tetrachloroaurate was reduced using sodium

. Exploring the Synthesis of Doped Nanorod Quantum Dots Hannah J. Johnson, Senior Capstone Seminar Nanocrystal quantum dots can be used for a variety of applications. The absorbance spectrum of these nanocrystals can be adjusted by changing their size, which includes both length and width. This research was performed to more fully understand the procedure of synthesizing ZnSe nanorod quantum dots by breaking down the reaction steps and adjusting the precursors and temperatures in the reaction. “Magic

- Colorimetric Biosensing Assay using Silver Nanoparticles for Detection of Aptamers and other Biological Targets Katie Cameron, Senior Capstone Seminar The purpose of this research is to recreate a colorimetric detection assay similar to literature and use silver nanoparticles instead of regularly used gold particles to detect DNA and other biological targets. to make this process cheaper/easier to perform. The basic experimental method includes the synthesis of silver nanospheres that are attached to a

Garling, Senior Capstone Seminar Colloidal semiconductor quantum dot properties depend on their surface ligands. Dithiocarbamate ligands are of particular interest due to their potential use in industry. Knowledge of how this ligand is binds to the crystal surface is lacking. TEADMPTC undergoes acid base chemistry in common solvents, producing multiple species in solution. 3:30-3:40 - Break3:40 pm - Insertion of Botryococcus braunii Race B SSL-3 Gene into a pETDuet-1 Vector for the Comparative
