Caltech Micromachining Laboratory In-flight blood analysis for astronaut health monitoring

This graph shows the four-part differential leukocyte count. Portable μ-flow cytometer for blood analysis

Project Abstract

In NASA human space missions, it’s an emerging topic how to handle health issues of astronauts during flight, where they lack diagnosis facilities. Blood analysis is a useful test for monitoring astronaut’s health status and providing diagnostic information. This project focuses on developing in-flight blood analysis with lab-on-a-chip technology. The goal is to develop a portable/handheld system for space application and point-care-application.
