A simple methodology to assess cell adhesion on materials was developed. We demonstrated that the cell adhesion strength could be quantified. Using this method, we were able to compare the NIH/3T3 Swiss mouse fibroblasts adhesion strength to poly(methyl methacrylate) and polycarbonate. A controlled fluid shear stress was applied to cells using a parallel plate rotational system. Cells detached from the surface in the radial direction. Results showed that there was a critical radius where the shear stress experienced by the cells equaled the cell adhesion strength. The cells outside this radius were removed while those inside maintained initial confluency. The quantitative evaluation of cell adhesion is beneficial for development of biomaterials.
