NIST researcher Ted Heilweil, National Research Council postdoctoral fellow Catherine Cooksey (pictured), and NIST Summer Undergraduate Research Fellow Ben Greer from Carnegie Mellon University have demonstrated the feasibility of a new technique for studying biomolecules using terahertz radiation. Because terahertz waves are almost completely absorbed by water, the team was able to reduce the amount of water to the bare minimum while still providing a realistic sample environment by using hollow, nanosized droplets called micelles as tiny test tubes.
