Cell viability assay of KLA peptide, KLAAm, and a library of KLA based peptide brush polymers with different grafting densities. Hella cells were treated with peptide based materials and incubated for 72 hours at 37°C (CellTilter-Blue assay, n = 3 independent experiments with three independent samples in each). KLA peptide and KLAAm did not exhibit cytotoxicity to Hela Cells even at a concentration of 100 μM. The IC50 value of peptide brush polymers decreased as the grafting density of peptide brush polymer increased, indicating a higher cytotoxicity of KLA peptide brush polymers with a more compact brush architecture.
