Figure 4

Kinetic study showing the crosslinking of biotinylated GNP in the presence of low streptavidin concentration (9 nM) confirming biotin-streptavidin interaction. Also shown as a dotted line is the non-crosslinked high concentration streptavidin (100 μM) coated GNP profile. Inset shows the initial non-crosslinked dispersed GNPs in the right and the final crosslinked settled GNPs in the left. Also shown in black dotted line is the streptavidin coated biotinylated GNPs (using high streptavidin concentration).
