Capture, isolation and electrochemical detection of industrially-relevant engineered aerosol nanoparticles using poly (amic) acid, phase-inverted, nano-membranes

- Exposure level assessment of aerosol nanoparticles reported using Harvard's VENGES.
- Device equipped with pi-conjugated conducting PAA membrane filters/sensor arrays.
- PAA membrane motifs used to capture, isolate and detect the nanoparticles.
- Manipulating the PAA delocalized π electron enabled electrocatalytic detection.
- Fe2O3, ZnO and TiO2 quantified using impedance spectroscopy and cyclic voltammetry.
