Flexible, wearable X-ray detector doesn’t require heavy
metals

X-ray imaging is a fast and painless way for doctors
to see inside a person. But radiation detectors, which go under the
body part being imaged, are rigid panels that contain harmful heavy
metals, such as lead and cadmium. Now, researchers in ACS’ Nano
Letters report a proof-of-concept wearable X-ray detector prepared
from nontoxic metal-organic frameworks (MOFs) layered between
flexible plastic and gold electrodes for high-sensitivity sensing
and imaging.
