Researchers 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.
Previous researchers have used MOFs for flexible radiation detectors because they are semiconducting materials that respond to electromagnetic radiation by creating an electrical current. However, some of these MOFs still include lead, just like the X-ray detectors that are currently in use. So, researchers in ACS’ Nano Letters wanted to create a heavy-metal-free MOF for a flexible X-ray detector and imager.
