A flow cytometer is an automated scientific instrument used to count and examine microscopic particles. Flow cytometery is commonly used in scientific research performed by microbiologists using laser beams.
Wolfgang GÃ¶hde developed the first flow cytometer utilizing “The Coulter Principle” for fluorescent flow cytometery devices in 1968. Before the introduction to fluorescent flow cytometer devices the most common method for examining microscopic particles was through absorption methods.
Flow cytometery has a wide use of applications in medicine including chemotherapy, hematology, and also genetics and semen cataloging for predetermining sexual orientation. Marine biologists sometimes use a flow cytometer to indicate the structure of certain marine life communities.
