Abstract

In this study a new dynamic measuring chamber for flat biomaterials allowing the estimation of cell adhesion on test surfaces by measuring the cell lost from surface contacting test blood under defined Theological conditions is introduced. This was achieved by constructing a test chamber permitting the contact of small amount of blood with a large geometrical test surface. The construction consists of a spiral-shaped flow channel of 0.3 cm width, 0.02 cm heigth and 78 cm length. The applicability of the new method was demonstrated by evaluation of platelet adhesion on siliconized glass, fibrinogen coated glass, cuprophane and polyacrylnitrile.
