摘要
The scale bars in Figures 2, S2B, and S13 should be labeled as “~270 µm”. The last sentence in the caption of Figure S13 should be “Blue area approximately indicates big microdroplets (approximately, =22 µm); green area, medium microdroplets (approximately, 22 µm, 8 µm); and red area, small microdroplets (approximately, =8 µm).” These corrections do not affect the conclusions of the paper. We apologize for any inconvenience.
