Understanding Polymer-Cell Attachment

The development of polymeric materials with cell adhesion abilities requires an understanding of cell–surface interactions which vary with cell type. To investigate the correlation between cell attachment and the nature of the polymer, a series of random and block copolymers composed of 2‐(dimethylamino)ethyl acrylate and ethyl acrylate are synthesized through single electron transfer living radical polymerization. The polymers are synthesized with highly defined and controlled monomer compositions and exhibited narrow polydispersity indices. These polymers are examined for their performance in the attachment and growth of HeLa and HEK cells, with attachment successfully modeled on monomer composition and polymer chain length, with both cell lines found to preferentially attach to moderately hydrophobic functional materials. The understanding of the biological‐material interactions assessed in this study will underpin further investigations of engineered polymer scaffolds with predictable cell binding performance. Well‐defined random and block copolymers from single‐electron transfer living radical polymerization are examined for their performance in the attachment and growth of HeLa and HEK cells. Cellular attachment can be controlled by the adjustment of the polymer structure, with correlations observed between cell attachment and monomer composition and distinguished polymer chain length.
