Abstract

While more than 90% of cancer deaths are due to metastases, our ability to detect circulating tumor cells (CTCs) is limited by low numbers of these cells in the blood and factors confounding specificity of detection. We propose a magnetic enrichment and detection technique for detecting CTCs with high specificity. We targeted both magnetic and surface-enhanced Raman scattering (SERS) nanoparticles to cancer cells. Only cells that are dual-labeled with both kinds of nanoparticles demonstrate an increasing SERS signal over time due to magnetic trapping.

Post-Doctoral Fellow Dr. Lian Willetts shines light on the frontiers of discovery

Dr. Lian Willetts was awarded 2nd place in the Falling Walls Lab Finale in Berlin representing Dr. John Lewis’ lab by presenting: “Breaking the Walls of Prostate Cancer Metastasis”

Lab Falling Walls is an international competition that challenges graduate students to showcase how their research is redefining their respective fields and breaking down the walls to the next major scientific breakthrough. The University of Alberta is one of 20 approved international events, and the Sept. 30 event saw 16 outstanding examples of graduate research. Dr. Willetts was awarded 1st place during this night.

International Labs and the Finale in Berlin

Falling Walls Lab is a global scale event that takes place in different vibrant cities around the world throughout the year. The Falling Walls Lab Finale is held each year in Berlin on 8 November. The Finale gathers 100 participants, among them all winners of the international Labs.
