Abstract :
This paper reports results demonstrating the ability to use single microfabricated silicon flow channels for the differential counting of granulocytes, lymphocytes, monocytes, red blood cells (RBCs), and platelets, in a sample of blood by means of laser light scattering. The microfabrication-based flow cytometer described does not rely on sheath flow in order to align the blood cells
