In‑Situ Fluidic Impedance Sensing Technology for Real‑Time PFAS Groundwater Monitoring (Fluidic Impedance Platform for In‑Situ Detection and Quantification of PFAS in Groundwater, Tech ID: 19‑014)
Technology Overview: This NJIT technology introduces a fluidic impedance–based sensing platform for the in‑situ detection and quantification of per‑ and polyfluoroalkyl substances (PFAS) in groundwater. The system integrates microfluidic channels with impedance spectroscopy to measure PFAS‑induced changes in electrical properties directly within environmental water matrices. By enabling real‑time, on‑site monitoring without the need for extensive sample collection or laboratory analysis, the platform significantly accelerates PFAS assessment and supports continuous groundwater surveillance at contaminated sites.
Industry Pain Point: Conventional PFAS detection relies on laboratory‑based analytical techniques (e.g., LC‑MS/MS) that are costly, time‑consuming, and poorly suited for continuous or field‑based monitoring, limiting the ability of regulators and site managers to rapidly assess contamination dynamics.
NJIT Solution: This platform leverages fluidic impedance measurements within a microengineered system to enable sensitive, quantitative PFAS detection directly in groundwater. The approach supports in‑situ deployment, reduces analytical turnaround time, and lowers monitoring costs while providing actionable, near‑real‑time data.
