Hydrodynamic focusing investigation in a micro-flow cytometer

Cells are counted as they are forced to pass through a small channel (often referred to as a flow cell), causing disruptions in a laser light beam or electricity flow. These disruptions are analyzed by the instruments. It is difficult to create tunnels narrow enough for this purpose using ordinary manufacturing processes, as the diameter must be in the magnitude of micrometers, and the length of the tunnel should exceed several millimeters. The standard channel size used in most … WebFlow cytometry is widely used in immunology and clinical testing, where blood cells are pretreated with several fluorescent markers, called fluorochromes, that are engineered to attach to various surface antigens on the blood cells. ... through a process called hydrodynamic focusing, to flow in single file through an interaction zone where they ... t-test scribbr
