Investigation of the Effect of Molecular Weight, Density, and Initiator Structure Size on the Repulsive Force between a PNIPAM Polymer Brush and Protein

Figure 5

A plot of force versus distance for a PNIPAM polymer brush-coated mica and bare mica surface in water. Dots are experimental data digitized from ref [29, 34ā€“37], and the solid line is a curve fitted to the data points (Equation (7)).
