PIPAAm grafted surfaces

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... [Pg.98]

HGURE 3.2.1 Temperature-dependent alteration of cell attachment and detachment on PIPAAm-grafted TCPS surface. [Pg.98]

Morra et al. first used a UV irradiation method (Morra Cassinelli, 1997 Von Recum et al., 1999) to graft PIPAAm on PSt substrate. IPAAm monomer and benzo-phenone (BP), a photoinitiator, is dissolved in 2-propanol solution and subjected to UV irradiation to prepare PIPAAm-based TRCS. PIPAAm-grafted PSt surfaces reveal TRCS by an L-929 mouse fibroblast ceU attachment and detachment assay. [Pg.210]
