Superfund Research Program
On-Site Detection of Benzo(a)pyrene in Water and Soil
Project Leader: Y. Andrew Wang
Grant Number: R43ES030664
Funding Period: Phase I: April 2019 - March 2020
Benzo(a)pyrene (BaP) is universally present in polycyclic aromatic hydrocarbon mixtures and is listed as a Group 1 carcinogen by the International Agency for Research on Cancer. Among the current 1,317 Superfund sites on the National Priorities List as of February 2017, BaP has been found at 524. There is an urgent need for development of a novel on-site assay for rapid, sensitive, reliable, and cost-effective identification and quantification of BaP in soil and water at Superfund sites. In this project, Ocean NanoTech will develop and commercialize a quantum dot-based quantitative FRET (QFRET) immunoassay for fast on-site detection of BaP. Compared to the existing technologies, the proposed platform assay will possess the following advanced attributes: high sensitivity, high specificity, fieldability, fast detection (minutes vs. days for lab test), ease of operation (wash-free, mix-and-read), and low operation cost. An anticipated product will be an evaluation kit including reagents, glass or plastic tubes, and a compact photoluminescent reader. The goal of Phase I is to demonstrate the feasibility of this novel assay platform. In Phase II, one of the aims will be to design a compact and inexpensive reader for on-site detection.
