Compact Surface Plasmon Resonance Sensor for Underwater Chemical Sensing Robot

Figure 13

Response of the SPR sensor to eight chemical substances listed in Table 1. Each bar shows the mean photocurrent for three repeated experiments. Error bars show the minimum and maximum of the three measurements. (a) Bare gold nanostructure. (b) Gold nanostructure coated with a self-assembled monolayer of 11-mercapto-1-undecanol.
