Multicomponent microenvironment sensing is crucial to a wide variety of industry and academic fields from industrial reactors to academic cell research. Real-time spatially resolved remote sensing methods are particularly powerful for investigations in a biologic context, especially targeted towards cellular metabolism. I have investigated the use of self-catalyzed magnetically guided micromotors for a ‘capture and detect’ method of direct separation of a target analyte using functionalizable surfaces. Fluorescent core/shell nanoparticles, also known as Cornell dots, are being used as the base for liquid phase detection of pH, partial pressure of oxygen and carbon dioxide with customizable surface chemisty. Surface-enhanced Raman spectroscopy is being investigated for non-perturbative small molecule detection using customizable surface monolayers as partition layer to detect glucose and lactic acid in solution via gold nanoparticles, as well as investigation of nanoporous gold thin films as stable SERS substrate for gas-phase sensing.
Previous research experience includes working under Professor Kristina Trujillo as a staff research assistant in the University of New Mexico’s Department of Biochemistry and Molecular Biology. The main project was investigating biomarkers for the recurrence in breast cancer in tissue margins, focusing on staining and image processing for the lab. Other duties including selecting appropriate tissue ductal structure from stored tissue blocks for tissue microarrays, cell culture for human surgical samples and stable human cell lines, and other microbiological techniques. Undergraduate research focused on investigating a quantitative field assay for capsaicin under Professor Murphy Brausel and the thermodynamic stability of DNA/RNA bulges under Professor Nina Grover at Colorado College.
