Description:
Due toiIncreasing concerns over long-term effects of PFOS and PFAS on human body,health based values were set by regulatory authoritalive bodies for drinking water standard. Currently lab-based PFOA and PFOS water tests cost $200 - $300 per sample with a turn around time of 2 -3 weeks. In this program, 2Wi Tech LLC proposes to develop a low-cost fieldable sensing technology for detecting trace amounts of PFOA and PFOS in water down to 10 ppt. This unique molecular imprinting based analytical technique , which does not require any complicated instrumentation , will utilize at inypolymeric chip to measure the concentration of fluorocarbons in aqueous solution. In Phase I, 2Wi Tech will develop a photonic crystal polymer sensor chip that exclusively binds PFOA and PFOS molecules inside its matrix and produces specific optical signals that can be construed using a UV - Vis spectrometer and correlated to the concentration of PFOA and PFOS in water. The proposed sensor will offer the following advanced attributes: high sensitivity, high speoiflcity, fast detection, ease of operation, low power consumption, zero chemical release, and low operation cost . As a potential customer, Carollo Engineers has shown interest to test the sensor in field.
