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.
Most X-ray detectors are integrated into big, immobile instruments, such as computerized tomography (known as CT) and mammography equipment, or are stiff, like the sharp-edged bitewing detectors used in dental offices. [Read more…] about Flexible, wearable X-ray detector doesn’t require heavy metals
