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.

Electroporation of HeLa Cells with Propidium Iodide using ""Anodisc"" Nanopore Inorganic Membrane-Buffered MEAs

Description
The use of microelectrode arrays (MEA) to electroporate cells is now a reliable way of transfecting RNA interfering substances with high viability and efficiency. However, as the 50-200 micron electrodes are coated with many cells, there are differences in both viability and efficiency between the outside and inside of the…

The use of microelectrode arrays (MEA) to electroporate cells is now a reliable way of transfecting RNA interfering substances with high viability and efficiency. However, as the 50-200 micron electrodes are coated with many cells, there are differences in both viability and efficiency between the outside and inside of the electrode. This is due to the field created by the electrode, which has higher intensities toward the outside and lower intensities toward the middle. In order to get the electric field to spread in a more even manner, an "Anodisc" inorganic membrane seeded with cells was placed on the MEA to act as a buffer to the electric fields. One hundred percent transfection efficiency on live cells was found on one sample, though there were problems encountered along the experimental process that introduced error into the results, some of which included the inability for cells to grow to high levels of confluency on the Anodisc as well as the inverted imaging technique used on the opaque disc.
