This Article contains two errors in the Discussion section under the subheading ‘Effect of material properties on the cell interactions’.

“In accordance with previous findings measured with a different method and other cell types74, we observed that the un-normalized adhesion of a polysaccharide with cells was very weak, only about 2 nJ for WA07 and 2.7 nJ for HepG2 after 30 s in contact (Table S1e,f)”

should read:

“In accordance with previous findings measured with a different method and other cell types74, we observed that the un-normalized adhesion of a polysaccharide with cells was very weak, only about 1.6 fJ for WA07 and 2.7 fJ for HepG2 after 30 s in contact (Table S1e,f)”.

Secondly,

“The corresponding un-normalized adhesion values for LN-521 interactions were 3.8 nJ for WA07 and 33 nJ for HepG2 (Table S1e,f)”

should read:

“The corresponding un-normalized adhesion values for LN-521 interactions were 3.8 fJ for WA07 and 33 fJ for HepG2 (Table S1e,f)”.

Additionally, the Supplementary Information that accompanies this Article contains errors in Table S1, S2 and S3.

In Table S1, the units of adhesion energy are incorrectly given as nJ instead of fJ. Additionally, three values of adhesion energy for CNF in panels (b), (d) and (f) are incorrect.

In Table S2, two values of radius are incorrect for CNF in panel (a) and Col I in panel (b).

In Table S3, the units of adhesion energy are incorrectly given as nJ instead of fJ.

The correct Tables S1, S2 and S3 appear below as Tables 13, respectively.

Table 1 Adhesion energies and maximum pull-off forces for HepG2 (a,c,e) and WA07 (b,d,f) cell interactions with collagen I (Col I), collagen IV (Col IV), cellulose nanofibrils (CNF), and laminin-521 (LN-521) at contact times of 1, 10 and 30 seconds. Mean values and standard errors of the mean (SEM) are shown.
Table 2 Radii (µm) of the used colloidal probes for force measurements between HepG2 (a) and WA07 (b) cells and collagen I (Col I), collagen IV (Col IV), cellulose nanofibrils (CNF), and laminin-521 (LN-521).
Table 3 Adhesion energies and maximum pull-off forces for HepG2 cell interactions with uncoated, APTES-coated, and PEI-coated glass probes after 1 s (a), 10 s (b), and 30 s (c) contact times. The radii of used colloidal probes (µm) are presented in (d). Mean values and standard errors of the mean (SEM) are shown.
