In the present work, blood plasma protein deposition to spontaneously air oxidized silicon, titanium and aluminium was re-investigated in vitro. Immunological- and null ellipsometry methods were used to detect and quantitate adsorbed proteins, RIA methods to study the retention of preadsorbed 125I-HSA upon exposure to buffer or blood plasma, and kallikrein-specific colorimetric substrate S-2302 to follow the surface generation of kallikrein. The results show that the contact activation of… CONTINUE READING
