2witech Solutions LLC develops a sensing film for the measurement of PFAS (per-and polyflueoroalkl substances) concentration. The company's solution offers rapid on-site detection of PFAS using a small sensing film that gets read by a handheld spectrometer and provides data on the concentration of PFAS. The firm's sensing films use an engineered nanostructure polymer layer on a clear substrate and has a detection limit as low as 10 ppt. The technology has applications for detection in groundwater, drinking water, wastewater, and other liquids.
