Error in Figure

In the original publication [1], there was a mistake in Figure 2 as published. The structures of hydroxypropyl-β-cyclodextrin and sulphobutyl-β-cyclodextrin were not representing the most chemically abundant species that are formed during the reactions of chemical substitution of OH groups by 2-hydroxypropyl and sulfobutyl residues, respectively. The corrected Figure 2 appears below this text.

Figure 2. Structural representation of β-CD and three of its derivatives: (2-hydroxy)propyl-beta-cyclodextrin (HPβCD), randomly methylated beta-cyclodextrin (RAMEB), and sulfobutyl ether β-CD (SBEβCD). The main skeleton of β-CD is represented in blue and the substituent groups are highlighted with different colours (carbon in grey, oxygen in red, hydrogen in white, sulphur in yellow and sodium in purple).
