Researchers develop new gel-based nanosensor for radiation dose monitoring
Therapeutic radiation treatment has to be done with extreme precision to be fully medically beneficial. Overdosing or underdosing in the use of high-energy radiation beams can each present serious risks to patients. Too much healthy body tissue can he destroyed by overdosing, while underdosing can do too little to remove a dangerous tumor. Kaushal Rege, a Fulton Schools professor of chemical engineering, along with research collaborators at a Banner MD Anderson Cancer Center in Arizona, are developing a hydrogel of gold salts and amino acids that can carefully measure doses of radiation by being applied directly to a patient’s skin.
