SRS images of the viable epidermis at the CH3-vibration mainly highlight proteins (left). A capillary with individual red blood cells (arrow) is visible. The cells are imaged without motion blur due to video rate acquisition speed. (right) An x-t plot acquired by line-scanning across a capillary at the position of the arrow. Individual red blood cells are captured on the fly. Scale: 25 μm (Image: Dr. Brian Saar and Christian Freudiger)
Article Summary
Scientists and MDs have a wide range of technologies available for the imaging of live tissue, but each of these comes with its own limitations - be it poor contrast, low resolution, long response times or the viewing process damaging the tissue being observed. A team of Harvard researchers has developed a new type of optical biomedical imaging that promises to overcome these obstacles and is so fast and high-resolution that it can capture live video of cells and molecules.
