Real-time monitoring of mechanical changes during dynamic adhesion of erythrocytes to endothelial cells by QCM-D.

A quartz crystal microbalance with dissipation monitoring is used to measure changes in mechanical properties of diabetic red blood cells (RBCs) and normal RBCs. Moreover, the adhesion interaction between these two kinds of RBCs and endothelial cells (ECs) is further investigated using a proposed QCM-D biosensor for the first time.
