Barrett

Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.

Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

Combined AFM and Fluorescence Measurements for the Investigation of Nanophotonic Effects on Single Fluorophores

Description
In this project, we introduce a type of microscopy which produces correlated topography and fluorescence lifetime images with nanometer resolution. This technique combines atomic force microscopy (AFM) and time resolved confocal fluorescence microscopy to conduct biological and materials research. This method is used to investigate nanophotonic effects on single fluorophores,…

In this project, we introduce a type of microscopy which produces correlated topography and fluorescence lifetime images with nanometer resolution. This technique combines atomic force microscopy (AFM) and time resolved confocal fluorescence microscopy to conduct biological and materials research. This method is used to investigate nanophotonic effects on single fluorophores, including quantum dots and fluorescent molecules. For single fluorescent molecules, we investigate the effects of quenching of fluorescence with the probe of an atomic force microscope which is combined and synchronized with a confocal fluorescence lifetime microscope. For quantum dots, we investigate the correlation between the topographic and fluorescence data. With this method of combining an atomic force microscope with a confocal microscope, it is anticipated that there will be applications in nanomaterial characterization and life sciences; such as the determination of the structure of small molecular systems on surfaces, molecular interactions, as well as the structure and properties of fluorescent nanomaterials.
