In the published version of Fig. 2, images at 1 h 0 kV and 10 kV overlap with image 5 kV. The corrected version of Fig. 2 shows new images for 1 h—0 kV and 10 kV. The authors regret their oversight during figure assembly and would like to sincerely apologize for this error. This unintentional error has no bearing on the article’s scientific conclusion.

These micrographs show the attachment and proliferation of the control and electrosprayed hASCs (the 5 and 10 kV groups); BES did not alter cell viability. In contrast, hASCs electrosprayed at 20 kV nearly always failed to attach and proliferate, confirming loss of viability. Scale bar 50 µm
