Analysis of size distribution of red blood corpuscles using surface Plasmon resonance sensor for medical diagnosis

摘要

The paper provides an analysis of different sizes red blood corpuscles (RBC) using surface Plasmon resonance (SPR) sensor. Change of RBC size affects the change of refractive index. SPR sensor is sensitive towards this small change of refractive index. A general formula is given in this paper such that just observing the output intensity of SPR sensor, the size of the RBC present as dielectric at the interface of metal in SPR sensor can be determined.
