Study Shows Ability of Red Blood Cells to Act Like A ‘Fiber-Optic Cable’

If you were to shine a light beam through a vial of blood, you’d see at most a dull, diffuse glow out the other side. But a new study by San Francisco State University researchers and an international team of collaborators shows that under certain conditions, lasers can cause fluid containing blood cells to act like a fiber-optic cable, preserving the focus of a laser beam and allowing it to shine through unimpeded. The surprising phenomenon could form the basis for new medical diagnostic techniques that take advantage of the properties of our own cells.
