Flow cytometry

Flow cytometry is like playing a game with colorful balls, but the balls are too small for you to see with your eyes. So, you have a machine that can see them for you!

You put a bunch of these tiny balls through a tube that is inside the machine. The machine then shines a laser beam on them, and as each ball passes by the laser, it gets excited and starts glowing a certain color.

The machine then quickly measures how bright the glow is and what color it is. This helps us figure out what kind of balls we have, how many of them there are, and how healthy they are.

It's like sorting a whole bunch of different Lego blocks into different colors and shapes, but instead of using our hands, we use a machine that can see tiny particles that are too small for us to see.

This information can help doctors and scientists learn about different types of cells in the body and how they work. It can also help them diagnose diseases and measure how well treatments are working.
