Abstract: Systems and methods are provided for degrading PFAS in a semi-solid sample. The semi-solid sample includes PFAS molecules in a partially liquid solution. An electron donor, and optionally a surfactant, are introduced into the mixture, forming micelles. An electron donor associates with the micelle surface and releases hydrated electrons upon exposure to UV light to initiate the reductive defluorination reaction, resulting in fluoride, water, and simple carbon compounds.

Abstract: The present disclosure relates to fluid treatment. In particular, examples of the present disclosure relate to devices, systems and methods for fluid treatment combining electrochemical oxidation treatment and sonication treatment of fluids.

Abstract: Disclosed herein are electrochemical-based sensors, comprising: a solid electrode material; a linker moiety bound to the solid electrode material; and a receptor bound to the linker moiety, wherein the receptor binds to a target, and the binding of target to receptor causes an increase in the charge transfer resistance of the solid electrode material. In particular, the present disclosure relates to an electrochemical sensor which is selective for the S1 subunit of the SARS-CoV-2 spike protein and which uses boron-doped diamond as a solid electrode material. Sensor networks comprising one or more such sensors are also disclosed herein, along with methods of detecting a target (e.g., SARS-CoV-2) using such sensors.
