Description:
Environmental nanotechnology—the science of engaging matter at the nanoscale level, and its potential application for “green” chemical products and processes, risk assessment, remediation, and exposure studies—offers a variety of new products and problems. Intentional or incidental release of these materials into the environment creates associated risks that are more difficult to monitor than those previously encountered. With this emerging technology, one area of specific interest to the EPA is the detection, accurate assessment and monitoring of engineered nanomaterials (ENMs). The desired detection technology should be capable of in-situ, remote and continuously determining the concentrations of these materials. In this presentation, we will describe the development of electrochemical quartz crystal microbalance sensor for continuous monitoring of engineered nanomaterials. This sensor is capable of distinguishing between engineered nanomaterials (e.g. hybrid organic metal nanoparticles), and naturally occurring nanomaterials (e.g. living bacteria and spores) that may be present in the environment.
