英文摘要
PROJECT 5: Nanotechnology-Based Environmental Sensing. Remediation of highly contaminated
Superfund sites requires monitoring and evaluation of the contaminants themselves and their byproducts.
Superfund sites have diverse and complex toxic species that contaminate soils, water and the surrounding
air; determining what is there, and then determining the extent and effectiveness of remediation continue to
present challenges. The rapid development of nanotechnology has offered significant opportunities to
produce new sensors for the characterization and monitoring needs of Superfund, not only in the gas phase,
but in the different environments where toxic and/or hazardous materials are produced or where they
accumulate. We will take advantage of the unique properties of nanoscale materials to detect and measure
species such as heavy metals. We plan to develop a collection of sensing protocols for the detection of
arsenic, mercury and flame retardant compounds with high sensitivity and specificity. We will develop and
apply small-molecule chemical indicators for fluorescence detection of mercury, lead, cadmium, and other
toxic heavy metals in environmental laboratory and field samples, with specific interest in seafood and soil
specimens. Parallel with this effort, plasmon absorption spectroscopy based on metal nanocrystals will be
used for low-cost, rapid detection of mercury in air and aqueous environmental samples. We will continue to
develop silver nanocrystal based substrates for ultra-sensitive arsenic detection using surface enhanced
Raman spectroscopy. We will extend this sensing platform towards detecting chemical fingerprint for the
analytes, distinguishing between the two most common oxidation states of arsenic: arsenate (As^) and
arsenite (As'") both in ground water and some other complex media. Similariy this sensing scheme will be
applied towards detection of methylated arsenic species with high sensitivity using small sample volume. In
addition, we will also develop a sensitive and selective miniaturized electronic sensor for environmental
toxicants molecules such as polybrominated diphenylethers (PBDE) using specific molecular recognition
elements. These studies should provide new methods to detect and measure chemical and biological
species at Superfund sites. The new methods will also be useful for assessing remediation efforts and the
reduction of hazardous species at known sources.
