Flow Cytometry: Revolutionizing Cellular Analysis and Diagnostics
Flow cytometry is a powerful analytical technology that allows scientists to study cells and particles at an individual level with remarkable precision. By combining principles of fluidics, optics, and electronics, this technique enables rapid and detailed analysis of multiple physical and chemical characteristics of cells suspended in a fluid stream. Over the past few decades, flow cytometry has become an indispensable tool in research laboratories, clinical diagnostics, and drug development due to its versatility and accuracy.
At its core, flow cytometry works by passing cells one by one through a laser beam. As cells intercept the laser, they scatter light and emit fluorescence if labeled with specific dyes or antibodies. The scattered light provides information about cell size and internal complexity, while fluorescence indicates the presence and quantity of targeted proteins or markers. This dual capability allows researchers to identify different cell populations…
