Figure 7

Plot of binding affinity ratio between AuNPs and chemically functionalized surfaces (AuNP- S A and AuNP- S D ). The binding affinity ratios are obtained from experiments such as SEM image, cantilever assay, and LFM. This analysis indicates that DOPA molecules are approximately 1.5 times stronger than amino groups in their adhesion property for the immobilization of AuNPs.
