Application of Long-Range Surface Plasmon Resonance for ABO Blood Typing

Figure 5

LR-SPR kinetic curve showing detection of red blood cells (RBCs) and regeneration of the surface using 20 mM NaOH. PBS buffer was used to obtain a baseline reading () and then RBC-A is bound on the Anti-A for ~5 min, before the surface is rinsed with PBS buffer (). Then, 20 mM NaOH is injected on the RBC-A/Anti-A surface, followed by the injection of PBS buffer ().
