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.

Congratulations to top alumni honour awardee Dr. Ron Moore

Congratulations to Dr. Ron Moore, ’80 BSc, ’86 MD, ’91 PhD, who will receive an Alumni Honour Award from University of Alberta President David H. Turpin during the Alumni Awards Ceremony on Monday, Sept. 24, 2018, at the Northern Alberta Jubilee Auditorium in Edmonton.
The Alumni Honour Award recognizes the significant achievements and contributions by University of Alberta alumni to their profession and their community. Dr. Moore has made significant contributions to advancing our knowledge and treatment of bladder, kidney and prostate cancer. He has studied and developed laser treatment as therapy for prostate and bladder cancer, and developed new drugs to improve prostate cancer radiotherapy outcomes. Dr. Ron Moore has also actively mentored and trained hundreds of students throughout his career as well as serving on the APCaRI leadership committee.

The community is invited to celebrate as Dr. Ron Moore receives this top alumni award!
Date: Monday, Sept. 24, 2018
Location: Northern Alberta Jubilee Auditorium (11455 87 Ave), Edmonton, Alberta
Time: 7 p.m. ceremony with dessert reception to follow
Cost: Free, register for tickets
