The development of sensitive, yet easy-to-use methods for the detection of actinides (uranium, plutonium, etc.) is of continual interest for ensuring nuclear safety, enhancing nuclear nonproliferation efforts, and tracking nuclear species in the environment. In this project, researchers from SRNL and Fayetteville State University explored using films based on titanium carbide nanoparticles ("MXenes") as sensing materials to support trace-level measurements. We showed that MXenes could be used to measure low levels of a test molecule (Rhodamine B). The signal was linearly dependent on concentration, indicating that the method could be used for quantitative measurements and not just detection. We identified several ways to make the films better able to support routine measurements. Once these improvements are implemented, we will demonstrate their use for measuring uranium under conditions typical for environmental samples and waste streams in nuclear materials processing facilities.
