Collaborative Research: A Nanostructure Sensor For Measuring Dissolved Iron And Copper Concentrations In Coastal And Offshore Seawater, Mark Wells, Carl Tripp

University of Maine Office of Research Administration: Grant Reports

Iron and Copper serve as key co-constituents for numerous enzymes in a wide range of biological systems, and their elevated or impoverished levels in aqueous systems have dramatic consequences at organismal, ecosystem, and human health scales. Over the last decade these effects have increasingly been recognized to be important in ocean systems. Identifying sites and times where these metals cause negative environmental outcomes is greatly hampered by their comparatively sparse datasets. This problem is a direct consequence of the analytical challenge of obtaining accurate Fe and Cu determinations in saline waters at very low (trace) concentrations, and the limitations of …
