PIPAAm grafted surfaces adhesion

How is temperature-triggered switching of cell attachment/detachment on PIPAAm -grafted surfaces achieved A schematic illustration of cell adhesion with different thickness of grafted PIPAAm is shown in Fig. 3.2.2. Cell attachment dramatically decreases on... 

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...
