RESUMO

The red blood cell (RBC) membrane contains proteins and glycoproteins embedded in a fluid lipid bilayer that confers viscoelastic behavior. Sialylated glycoproteins of the RBC membrane are responsible for a negatively charged surface, which creates a repulsive electric zeta potential (Z) between the cells.The compact layer of charge or Stern consists of ions rigidly bonded to the cell and the double layer includes ions diffusely distributed around the cell. The aim of this study was to measure the RBC double layer thickness of the charge (DLC) around the cell, zeta potential (Z) and cell aggregation force in agglutination potentiator solutions, using optical tweezers.
