Determining topographical radiation dose profiles using gel nanosensors: The routine measurement of radiation doses can be clinically challenging due to limitations with conventional dosimeters used to measure the dose uptake of external ionizing radiation. In a new study, Karthik Pushpavanam and an interdisciplinary team of researchers in the departments of Chemical Engineering, Molecular Sciences, Banner MD Anderson Cancer Center and Arizona Veterinary Oncology in the U.S. has described a novel gel-based nanosensor. The technology allows colorimetric detection and quantification of topographical radiation dose profiles during radiotherapy.
