Chirality is one of the significant biochemical signatures of life. Nearly all biological polymers are homochiral as they usually show high preference towards one specific enantiomer. This phenomenon inspires us to design biomaterials with chiral units and study their interactions with cells and other biological entities. In this article, through adopting three pairs of aliphatic amino acids with different hydrophobic side groups as chiral species, and using two adhesive cell lines as examples, we show that the chirality of polymer brushes can trigger differential cell behaviours on the enantiomorphous surfaces, and more interestingly, such chiral effect on cellular behaviours can be modulated in a certain extent by varying the hydrophobic side groups of the chiral moieties composing the polymers. This work not only proves the versatility of the chiral effect at the cell level, but also demonstrates a method to bridge the gap between organic signal molecules and biomaterials. It thus points out a promising approach for designing novel biomaterials based on the chiral effect, which will be an important complement for conventional strategies in the study of biomaterials. |
