Researchers at the University of Alberta, led by Roger Zemp, have developed a method using intense ultrasound to extract cancer biomarkers from cells noninvasively, reducing the need for biopsies. This process, known as sonoporation, creates temporary pores in cell membranes, releasing biomarkers like miRNA, mRNA, and DNA into the bloodstream for detection. Presented at a joint meeting of the Acoustical Society of America and the Canadian Acoustical Association, this technique enhances biomarker levels in blood samples by over 100 times, enabling affordable and sensitive cancer detection and monitoring. This innovative approach offers a less invasive, cost-effective alternative to traditional biopsies, potentially transforming cancer diagnosis and treatment.
