The authors regret that there was a mistake in reporting the mol% of the microbubble coating composition used. For all experiments, the unit mg/mL was used, and the conversion mistake occurred only when converting to mol% to define the ratio between the coating formulation components. The correct molecular weight of PEG-40 stearate is 2046.54 g/mol (Shen et al. 2008; Kilic and Bolukcu 2018), not 328.53 g/mol. On page 494, the sentence should read “The coating was composed of 1,2-distearyol-sn-glycero-3-phosphocholine (84.8 mol%; P6517, Sigma-Aldrich, Zwijndrecht, The Netherlands); polyoxyethylene-40 stearate (8.2 mol%; P3440, Sigma-Aldrich); 1,2-distearyol-sn-glycero-3-phosphoethanolamine-N-[methoxy(polyethylene glycol)2000] (DSPE-PEG(2000); 5.9 mol%; 880125P, Avanti Polar Lipids, Alabaster, AL, USA); and DSPE-PEG(2000)-biotin (1.1 mol%; 880129C, Avanti Polar Lipids).” This correction does not change the conclusions published in this work.
