Figure Lengend Snippet: The sensitivity of the SPR imaging system. The refractive index was adjusted using a series of different concentration NaCl solutions. A 1 mW 680 nm SLED light source was used with a 12-bit CMOS camera and a 3.5 ms exposure time. The sensitivity in RIU was calculated as 2 × 10 −5 .
