The hemolytic properties of amorphous silica and MCM-41-type mesoporous silica nanoparticles (MSNs) with rabbit red blood cells (RBCs) are compared. The amorphous silica exhibits a high hemolytic activity toward the RBCs. In contrast, a high biocompatibility between the MSNs and the RBCs is observed. The low hemolytic activity of the MSNs offers promising potential for various in vivo biotechnological applications.
