Average frequency changes 30 min after injection of 250 μL PAO1 over bare and MEG-OH coated crystals at various flow rates, and the percent reduction in frequency change caused by the MEG-OH coating
| Flow rate (μL/min) | Bare crystal ΔFrequency (kHz) | MEG-OH crystal ΔFrequency (kHz) | Reduction in change (%) |
|---|---|---|---|
| 50 | 3.25 ± 1.08 | 0.22 ± 0.63 | 93% |
| 75 | 6.89 ± 5.00 | 0.75 ± 0.70 | 89% |
| 100 | 2.72 ± 1.83 | 0.40 ± 0.34 | 85% |
| 150 | 1.56 ± 1.47 | 0.18 ± 0.28 | 89% |
| 200 | 1.50 ± 1.55 | 0.05 ± 0.05 | 97% |
