Figure 7From: Effective polyethylene glycol passivation for the inhibition of surface interactions of peripheral blood mononuclear cells and platelets Radial displacement of PBMC on modified surfaces. The displacement is plotted over time for three PEGylated surfaces of the same batch (A-C), a piranha treated cover slip (D) and a bovine serum albumin (BSA) covered cover slip (E). 14 randomly chosen cells are plotted for each surface. Most PBMC are mobile on PEGylated surfaces (A-C), while most are locally fixed on BSA (E) and basically all immobilized on glass (D).Back to article page
