Agnirva Space Premier League - Expedition #31361: Pocket-Sized Labs in Space: Microflow 1 Technology Demonstration

What if astronauts could run blood tests in orbit with a device no larger than a lunchbox? The "Microflow 1 technology demonstration" explores this possibility.

Developed by INO and led by Dr. Luchino Cohen at the Canadian Space Agency, Microflow 1 is a compact, portable flow cytometer. Flow cytometry is a technique that analyzes the physical and chemical characteristics of cells or particles in a fluid. It’s a powerful diagnostic tool, often used in hospitals.

Before Microflow, astronauts had to send samples back to Earth for analysis, delaying diagnosis and treatment. But Microflow changes that. Tested during Expeditions 33/34 and 35/36, it proved that astronauts could perform real-time biomedical diagnostics on the ISS.

This space-based flow cytometer analyzes blood cells, detects infections, and monitors immune function—all without bulky lab equipment. It’s a game-changer for long-duration missions where timely diagnostics are essential.

The success of Microflow 1 paves the way for other miniaturized lab technologies that can work in remote or extreme environments on Earth. Think disaster zones, remote villages, or even battlefield medical tents.

With space tech shrinking and smartening, Microflow 1 shows that sometimes, the smallest tools can make the biggest impact.
