Claim 14:
15. A method, comprising:
detecting per- and polyfluoroalkyl substances (PFAS) in a sample by
flowing the sample through a channel of a device according to claim 1 thereby sorbing PFAS to the probes disposed in the channel;
applying an electric field across the sensing region;
obtaining a post-sample electrochemical impedance spectrum (EIS) of the sensing region; and
comparing the post-sample EIS of the sensing region to a pre-sample EIS of the sensing region obtained prior to flowing the sample through the channel, wherein a difference between the post-sample EIS and the pre-sample EIS indicates presence of the PFAS in the sample.
