Barrett, The Honors College Thesis/Creative Project Collection
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.

DNA is useful for electronic applications due to its self-assembly and electronic properties. It can be improved for this purpose through the addition of metal ions. In this experiment, DNA was modified with silver ions and carbon nanotubes were attached to both ends. The DNA-CNTs were connected over a 300 nm gap between gold electrodes using cysteamine. The conductance was found to be 1.28*10-4 G0, which is similar to literature values for unmodified DNA. Therefore, modifying DNA with silver ions was not found to significantly improve the conductance. It was also found that smaller applied voltages need to be used because of electrochemistry happening above 1 V.
