Researchers at the University of Illinois at Urbana-Champaign have developed a disposable sensor for detecting hazardous uranium ions, with sensitivity that rivals the performance of much more sophisticated laboratory instruments.According to the researchers, the sensor provides a fast, on-site test for assessing uranium contamination in the environment, and the effectiveness of remediation strategies.
While most DNA is double stranded, the catalytic DNA the research group used has a single strand region that can wrap around like a protein. In that single strand, the researchers fashion a specific binding site — a kind of pocket that can only accommodate the metal ion of choice.
