From the grafting density Γ, the root-mean-square distance between anchor sites (drms) of the glycopolymers was determined. In well-solvated polymer brushes, the average distance between anchor sites is equivalent to the mean spacing between polymers to a first approximation, that is, drms here represents a measure for the mesh size of the glycopolymer brushes. It can be seen that the mesh size (~5 nm; Table ) is comparable to the hydrodynamic diameter of the toxin B5 molecules (~5.5 nm) . This implies that any steric constraint imposed by the brush on the movement of toxins is rather moderate. Table further shows salient features of the target glycans, such as their projected surface density, concentration, and root-mean-square distance, in the brushes. One can see here that target glycan concentrations of several tens of mM are readily achieved, and that the average distances between target glycans (~4 nm; Table ) are also comparable to the typical distance between binding sites on the toxin molecules (~3 nm), implying that a toxin should be able to reach multiple target glycans without substantial re-organization of the glycopolymer brush.
