The authors regret that there was a mistake in reporting the mol% of the microbubble coating composition used. For all experiments, the unit in mg/mL was utilized, 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 1610, the sentence should read “The coating was composed of DSPC (84.8 mol%; P6517, Sigma-Aldrich, Zwijndrecht, The Netherlands); PEG-40 stearate (8.2 mol%; P3440, Sigma-Aldrich); 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.

The authors apologize for any inconvenience caused.
