Light couldn’t do it, but sound, proteins and bubbles could. 🔬🎵🫧 A new technique developed by David Maresca and his team at TUDelft lets us see cell populations and capillaries deep inside living organs, non-invasively. This incredible advancement in imaging technology uses tiny air-filled particles—think of them like super small balloons—that bounce back sound waves and allow researchers to track individual cells, including cancer cells, in real-time. This breakthrough allows for high-resolution, non-invasive imaging of cells and tissues, which could lead to earlier diagnosis of small vessel diseases and better monitoring of how cancer spreads.
