Key project activities include: Integrating microfluidic sensors for rapid PFAS detection, field sampling of biofilms and macroinvertebrates, identifying factors influencing...
This $620,000 federal Project Grant award from the U.S. Geological Survey's Assistance to State Water Resources Research Institutes program (CFDA 15.805) will fund a research project conducted by Clemson University, in collaboration with the University of South Carolina, to determine the fraction of total organic fluorine (TOF) in U.S. surface waters attributable to per- and polyfluoroalkyl substances (PFAS) versus fluorine-containing pharmaceuticals and pesticides. The 3-year project will...
The National Science Foundation awarded a $465,181 Project Grant to the University of Illinois under the Engineering federal grant program (CFDA 47.041) for the period of September 1, 2022 through August 31, 2025. The grant funds the development of a low-cost microelectrode sensor array platform coupled with machine learning algorithms to detect per- and polyfluoroalkyl substances (PFAS) in water. PFAS are a class of chemicals used in numerous consumer and industrial products that can...
The National Institute of Environmental Health Sciences (NIEHS) awarded a $587,600 Project Grant under the Environmental Health federal grant program (CFDA 93.113) to Nanoaffix Science LLC to develop a proof-of-concept technology for the rapid, low-cost detection of per- and polyfluoroalkyl substances (PFAS) in water. The project aims to create a graphene-based sensor chip and portable handheld detector capable of measuring PFAS concentrations down to 1 ng/L (parts per trillion) within 50% of...
This National Science Foundation (NSF) Project Grant award, under the NSF Directorate for Engineering (CFDA 47.041), will provide $212,973 to the University of Utah from July 2023 to June 2026 to conduct collaborative research on the molecular and nanoscale structure and interactions of per- and polyfluoroalkyl substances (PFAS), also known as "forever chemicals." The research will investigate PFAS surfactants in aqueous solutions and at water-air, water-oil, and water-solid...
The University of Tennessee, through the Board of Regents Tennessee, was awarded a $558,912 Project Grant by the U.S. Geological Survey under the Assistance to State Water Resources Research Institutes program (CFDA 15.805). The grant will support the development of a portable, on-site sensor platform for the rapid and sensitive detection of per- and polyfluoroalkyl substances (PFAS) in environmental media such as water, soil, and sediment. The project aims to create a user-friendly, cost-effective, and energy-efficient system that can detect PFOS, PFOA, and total PFAS at part-per-trillion levels, with high specificity. The system leverages the university's expertise in AC electrokinetic capacitive sensing technology and is expected to significantly improve environmental monitoring and management of PFAS contamination, contributing to public health and sustainability. The project period runs from January 1, 2024, through December 31, 2025.
