Title: Metal Ion Analysis Using Near-Infrared Dyes and the ''Laboratory-on-a-Chip''

Abstract

The primary objective of this project is to develop a sensitive and selective, portable sensor for radionuclides and heavy metals that utilizes a ''laboratory-on-a-chip'' platform for enabling low-cost, timely characterization of DOE remediation sites. The DOE has been tasked to deactivate and/or decommission nearly 10,000 buildings at 3314 EM release sites, and new analytical characterization tools are necessary in order to assist in the segregation of contaminated and non-contaminated scrap metal and concrete materials via the identification of the type and extent of radionuclide and heavy metal contamination apparent on these building materials. Current characterization techniques for radionuclides and/or heavy metals typically require lengthy analysis times at external laboratories, causing costly delays from a health and fiscal standpoint. This research objective will be accomplished by either synthesizing a new class of metal complexation ligands that are covalently linked to red fluorescing dyes, or by taking advantage of commercially available, red-shifted colorimetric metal complexation ligands, and utilizing these dyes for the selective quantitation of target metal pollutants through their selective separation down the microchannel of a ''laboratory-on-a-chip.'' Inexpensive, compact light sources will be utilized as excitation sources, and detection will be achieved using compact, inexpensive, photodiode array detectors.
