Poly(ethylene glycol)-b-poly(2-amino ethyl methacrylate)-b-poly(coumarin methacrylate) (PEG-b-PAEMA-b-PCMA) micelles were sampled onto silicon nitride (SiN) string resonators by electrospraying for 5 min, using different flow rates. The initial micelle sample in solution had a concentration of 1 mg/ml. Fig. 4 shows three strings, all 5 μm wide, 50 μm long and 100 nm thick, sampled using velocities of 50, 100, and 185 m/s, respectively. The figure correlates well with Eq. (3), which predicts the number of particles collected on a resonant filter-fiber per time to increase quadratically with the aerosol velocity. When increasing the velocity from 50 to 100 m/s, the increase in number of collected particles is negligible, except for a small edge effect. However, upon increasing the velocity from 100 to 185 m/s, the increase in deposited material is quite heavy. Fig. 5 shows two narrower strings, 1000 nm wide, but with the same length and thickness as the strings shown in Fig. 4, sampled at 50 and 100 m/s, respectively. Sampling is seen to be more efficient on the narrow strings compared to the wider strings, consistent with Eq. (2), and the effect of increasing the velocity from 50 to 100 m/s is also more pronounced, as expected.
