Abstract

Atomic force microscope (AFM) force measurements were taken on an alginate-polymer brush in varying pH buffer solutions in order to determine the meaning of the variable s in the force model. The current understanding is that s is the root spacing of the polymers, but this experiment suggests that s is the mesh spacing. The force curves were fit in order to determine the brush parameters. It was found that all parameters increased as a function of pH.
