Surface Plasmon Resonance System for Blood Protein Sensing (image) The Optical Society Share Print E-Mail Caption Illustration of the Surface Plasmon Resonance (SPR) system for selective blood protein sensing. Detection and monitoring is achieved through measuring the degree of reflected light from a disposable functionalized SPR microfluidic chip. The measured reflectance signal is directly related to the conditions for excitation of surface plasmons at the gold surface caused by the degree of thrombin binding.
