- Abstract
The mechanical properties of adsorption layers in small volumes (0.1 ml) of protein solutions in a saline are studied using small-diameter indenters. In an albumin solution, the partial substitution of the protein by an equivalent (by weight) amount of immunoglobulins G or M reduces the surface energy, whereas the addition of fibronectin improves the mechanical strength of the layer. The data obtained may provide a deeper insight into the mechanisms of specific dynamic processes responsible for the structuring of biological fluids in drying drops. In particular, such information is of value for medical diagnosis.
