Abstract: A new kind of miniaturized surface plasmon resonace(SPR) sensor was developed by using an optical resin synthesized in our lab as the transducer prism and a linear charge coupled device(CCD) as the detector. The sensitivity, resolution and linear dynamic range of the sensor were discussed. The sensor has been used to determine alcohol and KH2PO4 in water, and the results were satisfactory.

Key words: Surface plasmon resonance, Biological sensor, Linear CCD, Organic optical resin
