New Microscope Enables Needle Free Blood Testing
Medgadget, Gavin Corley, May 23, 2012-
For most people blood tests are synonymous with needle-sticks. However, researchers from the biomedical engineering department at the Israel Institute of Technology (Technion) may have found a way to take the pain out of some of our blood tests in the future.
The microscope uses spectrally encoded confocal microscopy (SECM), a technique which allows for 2D spatial imaging of the blood cells. In order to image the moving blood cells, a probe is pressed against the skin which generates a line spectrum of light from red to violet. As blood cells near the surface of the skin cross the projected spectrum they scatter the light, which is collected by the probe and analyzed to generate 2D images of the blood cells.
