The ability to monitor hematology parameters during spaceflight is currently an unmet medical requirement (NASA-STD-3001). This project evaluated a DNA stain/CCD camera based technology to provide a White Blood Cell count + differential (granulocytes, lymphocytes, monocytes, eosinophils, basophils) analysis during microgravity conditions.
Spaceflight results in adverse health effects on the human body. These effects may result in increased clinical risk to crewmembers participating in exploration-class deep-space missions. For clinical monitoring of astronauts and for in-flight biomedical research, laboratory instruments must be designed which function in the spaceflight environment. Currently there is no instrument capable of generating a white blood cell (WBC) count and differential during spaceflight, even though this is an existing National Aeronautics and Space Administration (NASA) medical requirement. We evaluated a new commercial analyzer in the context of spaceflight requirements and compatibility with the zero gravity environment. Reduced gravity analysis was performed during terrestrial parabolic flight. The analyzer was found to uniquely meet the basic requirements for spaceflight and should be appropriate for measuring WBC parameters onboard the International Space Station.
We anticipate the technology may have use onboard ISS for both medical diagnosis or research studies.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
