Recovery of Zn2+ ions from water samples by use of the nanopore stochastic sensing method. Each experimental value represents the mean of three replicate analyses ± one standard deviation. The experiments were performed at +120 mV in the presence of 5 μM LAQAVRSSSARLVFF and 0.25 μg/mL ADAM17.
| Sample type | Theoretical value (μM) | Experimental value (μM) |
|---|---|---|
| Tap | 1 | 0.99 ± 0.04 |
| Spring | 1 | 0.99 ± 0.03 |
| Lake | 1 | 1.04 ± 0.01 |
