Self-Contained Device Isolates Biological Samples

A patented self-contained device for isolating deoxyribonucleic acid (DNA), ribonucleic acid (RNA), proteins, and cells without using pipettes or centrifuges has been developed at NASA’s Johnson Space Center (JSC). Composed of reagents, functionalized membranes, and multi-way valves and pumps, this fluidic system enables automation of highly accurate real-time polymerase chain reaction (PCR) technology to isolate genetic material from organisms and microorganisms for molecular analysis. The device is self-enclosed and leak-proof, so users are protected from chemically hazardous reagents.
