Polymer graft density

In addition to the polymer grafting density, polymer molecular weight is another important molecular parameter that profoundly influences the properties of surface-anchored polymers. As discussed earlier, the thickness of...

Xue et al. have investigated the effect of graft PIPAAm brnsh density on the resulting cell adhesion character in terms of the number and occnpied area of adhered cells, and the circularity of the cells, and they find the correlation of the polymer graft density with cell attachment and detachment character (Choi et al., 2012 Xue et al., 2012). They prepare TRCS on a self-assembled monolayer formed silicon surface, where various polymer densities are grafted by using surfaces initiated ATRP method. On TRCS with a dense polymer brush (0.11 chains/nm ), a lower circularity is found in attached cells having an extremely poor cell adhesive character. When the polymer...
