Abstract
The PANI/Gr-SPE-devices displayed linear responses to estrogenic substances, in EIS assays, from 0.0975â¯ng/L to 200â¯ng/L in water samples, with a detection limit of 0.043â¯pg/L for E1, 0.19â¯ng/L for E2 and 0.070â¯pg/L for EE2 which is lower than other current biosensing techniques. This portable, disposable immunosensor offers a solution for immediate measurement at sample collection sites, due to its excellent sensitivity and selectivity when testing water samples obtained directly from rivers and waste water treatment facilities. The simple screen printing production method will enable the low cost, high volume production required for this type of environmental analysis.
