[Viscoelastic characteristics of protein solutions and micromechanics of their motion in porous carriers].
The interactions of model proteins with the templates of porous carriers in biosensors were analyzed in terms of events occurring during the molecular contact of biopolymers with a solid. The viscoelastic properties of casein and albumin at small widths of the layer of the solution applied to the crystal were estimated using the dynamic method of piezoqartz resonator. The experimental data on the viscoelastic characteristics of protein solutions of different concentrations were compared with the characteristics of their tangential motion in porous carriers from cellulose nitrate. It was found that the parameters of dynamic viscosity correlate with the time of motion of protein solution in a porous polymeric carrier.
