Sound waves may hold potential to diagnose whether tumour will spread

Scientists from Massachusetts Institute of Technology (Cambridge, MA), Pennsylvania State University (University Park, PA), and Carnegie Mellon University (Pittsburgh, PA) have collectively published a paper on cell separation using sound waves. The study initially focused on separating tiny plastic beads varying from 7.3 to 9.9 microns in diameter, resulting in 97% sorting accuracy. They then moved on to separating white blood cells (20 microns) and MCF-breast cancer tumour cells (12 microns), achieving 71% accuracy. The potential for this tool holds great significance in the medical field as finding tumour cells in the blood indicates the spreading of a tumour. When a tumour is about to spread, some cells migrate into the blood via a process called extravasation and travel to another site in the body. Continue reading
