Thin Film Could Lead to Hand-Held Cancer Detector

Jan-24-16 A thin, flexible film able to detect cancer biomarkers in the blood could open the door to smaller and more affordable diagnostic technologies.

Created by a team from the University of Michigan, the film is able to produce helix-shaped coils of circular polarized light, which is key to detecting cancer biomarkers in the blood. The technology of using circular polarization in cancer detection is still somewhat new, and previously required large and expensive machines for production. The new film, however, takes advantage of gold nanoparticles, which the team says are very good at polarizing the required light as well as self-organizing into the S-shaped chains that induce circular polarization.
