UCLA researcher Dr. Aydogan Ozcan images thousands of blood cells instantly by placing them on an off-the-shelf camera sensor and lighting them with a filtered-light source (coherent light, for you science buffs). The filtered light exposes distinctive qualities of the cells, which are then interpreted by Ozcan's custom software. By analyzing the cell types present in a much larger sample, a more accurate diagnosis can be made in a matter of minutes. No more sending blood away to a lab and waiting days or weeks for the results.
Ozcan is seeking a manufacture so these devices can be mass-produced. Link -Thanks, Dave Bullock!
