Slope values obtained with the DNA sensor for the calibration plots obtained for synthetic target RASSF1A prepared in buffer and in different biological samples and results obtained in the recovery studies performed with the developed DNA sensor in samples spiked with 2.5 nM of the synthetic target RASSF1A.
| Medium | Slope, nA µM−1 | Recovery(n=3), % |
|---|---|---|
| Buffer | (98 ± 1) × 104 | 101 ± 4 |
| Serum 25% | (76 ± 7) × 104 | 97 ± 5 |
| Saliva 25% | (98 ± 14) × 104 | 95 ± 6 |
| Urine 25% | (72 ± 6) × 104 | 94 ± 7 |
