  6. ing the binding of analytes to a surface, successfully immobilizing the ligand is obviously important. Significant development has occurred in this area, and so a number of immobilisation techniques are available to choose from. Next to the 'traditional' covalent coupling (in which the ligand is randomly immobilized across the sensor surface), it is also possible to.
  7. Consequently, SPR biosensors have been studied extensively since the first demonstration in 1982. More recently, biosensors based on localized surface plasmon resonance (LSPR), a SPR phenomenon observed in metallic nanostructures rather than bulk metal, has emerged as a leading label-free biosensing technique. The progress has been fueled by continual improvement in fabrication of metal.

In a typical Surface Plasmon Resonance (SPR) experiment, one molecule, the ligand, is coupled to the sensor surface. A solution containing the second molecule (the analyte) then is flowed over the surface. This creates a mass change on the sensor surface as the two molecules interact, which is detected in real time. Researchers can use these data to extract a detailed picture of the. development of SPR biosensors is to introduce an analytical instrument offering low cost, small size, quick and easy use, as well as a sensitivity and selectivity greater than the current instruments.
