Table 1.
Estimation of the MALDI-TOF MS minimal detectable concentration for CTB bound to 1 mol% GM1 in poly(bis-SorbPC) PSLBs.a
| Concentration of CTB (nM) | Frequency of samples that gave a S/N ≥ 3b | Number of silicon wafers prepared |
|---|---|---|
| 1 | 0/10 | 2 |
| 2 | 8/16 | 3 |
| 3 | 11/15 | 3 |
| 4 | 9/9 | 2 |
| 5 | 10/10 | 2 |
a
This table focuses on a narrow CTB concentration range that was identified from screening samples over a larger concentration range.
b
Frequency is reported as the number of samples in which CTB was detected/total samples that were analyzed.
