Uncoated quartz resonator as a universal biosensor.

We studied dynamic processes in drying drops of model protein-salt solutions, using an uncoated quartz resonator as a biosensor. To measure these processes we developed a method based on recording the dynamics of the Acoustic-Mechanical Impedance (AMI) of a drop as it dried on the surface of a quartz resonator oscillating at a resonant frequency of 60 kHz. The aim of this work was to highlight the role of some components of serum in self-organization processes.
