Abstract

A three‐step approach to tailor cell adhesion via surface‐grafted polymer gradients is shown in this image from the work of Genzer and co‐workers on p. 2802. Surface‐anchored polymer assemblies with gradients in polymer molecular weight and/or grafting density are first employed to tailor adsorption of the protein, which in turn governs the number density as well as the extent of spreading of osteoblastic cells. Increasing the surface coverage of the polymer results in a decrease in the amount of protein adsorbed, which causes a decrease in the number of cells adhered and a change in cell morphology.
