Microsensors for In-situ Chemical, Physical, and Radiological Characterization of Mixed Waste
A wide spread need exists for a portable, real-time, in-situ chemical, physical, and radiological sensors in characterization of mixed waste, ground water, contaminated soils and process streams. None of the currently available technologies offer a clear path to the development of sensors that are miniature, cost-effective, selective, highly sensitive with a wide dynamic range, and with the ability to work in air or liquid while providing chemical , physical, and radiological information. The goal of this project is to develop a single-sensor platform approach that is based on the recently discovered extreme sensitivity of microcantilever sensing using adsorption-induced forces. The objective of this research is to gain better understanding of the basic mechanism of adsorption-induced differential surface stress variation and to use this concept for developing sophisticated microsensors for chemical and radiological sensing in liquids.
