Microsensors for In-Situ Chemical, Physical, and Radiological Characterization of Mixed Waste

[摘要] The objective of this research program is to conduct the fundamental research to develop extremely sensitive and highly selective for chemical, physical, and radiological characterization of mixed waste and ground water using microcantilever platform. The microcantilever sensors have sensitivity in the range of parts-per-trillion. These sensors will be of great value to DOE for the safe and cost-effective in situ, real-time characterization of contaminated sites. The ability to detect and measure specific chemicals and radionuclides in real-time using miniature and inexpensive sensing device could result in considerable benefits with regard to both cost savings and safety issues. In addition, this approach can also lead to multi-element/multi target sensors using array approach. The selectivity of the sensor results from chemical modification of cantilevers using selective molecular recognition agents.
