Our proposed project, "Gold nanoparticle-based mercury analyzer for on-site measurement of soil and sediment," will develop and test the feasibility of nanoparticle- based mercury sensors for on-site measurements. Our focus is on adapting the technique to accommodate soil and sediment samples from contaminated sites. Immediate, highly accurate, and sensitive measurements of mercury contamination at sites are the best option. But the high-cost, low portability and low sensitivity of the available instruments often force investigators to collect samples and send them to labs to be analyzed. Gold nanoparticle-based plasmonic mercury sensing is inexpensive, ultra-sensitive, and ideal for portable applications. Using off-the-shelf components, Picoyune will design and build a lightweight (<20 lbs) and low power sensor that can replace time consuming and costly laboratory methods. The prototype sensor will be tested for feasibility and compared to the other commercial options. The development of such a commercial analyzer will benefit those parties concerned with monitoring and remediation of contaminated sites as well as all groups who monitor mercury. Mercury monitoring costs hundreds of millions of dollars each year across diverse scientific, regulatory, and industrial groups. The fundamental issue they all face is protecting human health and the environment from the risks of mercury pollution.

Public Health Relevance

We are developing a portable gold nanoparticle-based mercury monitor for soil and sediment measurements at contaminated sites that will be more sensitive and less expensive than the commercial alternatives. Better monitoring will improve the remediation efforts and ensure that the public is protected from mercury, a potent neurotoxin.
