Abstract
Correction for ‘Addressing challenges in the removal of unbound dye from passively labelled extracellular vesicles’ by Kaisa Rautaniemi et al., Nanoscale Adv., 2022, DOI: 10.1039/d1na00755f.
The authors regret that an incorrect version of Table 3 was included in the original article. The correct version is given here:
| Dye | Method | 110k EVs | 20k EVs | ||||
|---|---|---|---|---|---|---|---|
| R EV (%) | R dye (%) | E rp , | R EV (%) | R dye (%) | E rp , | ||
| a † – acceptably high; ‡ – unacceptably low; all other values are acceptable with caution. b E rp > 1 indicates successful separation of the labelled EVs from the unbound dye: the greater Erp, the better separation; conversely, Erp < 1 indicates unsuccessful removal of the dye. | |||||||
