A thin, stretchable film that coils light waves like a Slinky could one day lead to more precise, less expensive monitoring for cancer survivors. The University of Michigan chemical engineers who developed the film say it could help patients get better follow-up treatment with less disruption to their everyday lives.
The film provides a simpler, more cost-effective way to produce circularly polarized light, an essential ingredient in the process that could eventually provide an early warning of cancer recurrence.Image credit: Joseph Xu, Michigan Engineering Communications & Marketing
