Multidimension potential of surface plasmon resonance imaging for dynamic surface characterization: application to optical biochips

摘要

We have realized a surface plasmon resonance imaging system allowing accurate characterization of biochips. In this paper, the Rouard approach is extended to absorbing layers to model the reflectivity information contained in the multidimensional data. The multidimension potential is also expressed to demonstrate the power of the SPR imaging system. To conclude, towards the development of a biosensor based on SPR, a theoretical study is also performed on the sensitivity to changes in reflectivity of such multidimension optical biosensor. The sensitivity of the sytem shows the power of this biophotonic technology.
