Abstract

The present invention relates to an online biosensor system and method for combined real-time UV-light monitoring and nanoplasmonic sensing based on LSPR. The biosensor system comprises a sensor module, a light source module, optical fiber module and a detector module. The sensor module comprises at least one sensor chip which is contact with a sample. A first sensor chip of the sensor module comprises a surface and plasmonic nanoparticles. The plasmonic nanoparticles are immobilized on said surface or alternatively on an optional substrate configured above said surface. The nanoparticles capture molecules, such as the antibodies, and said molecules have specificity for one or more analytes. The light source module emits a first light in the UV light region as well as a second light in the visible region or in the near-infrared region. The optical fiber module comprises at least one optical fiber which is connected to the sensor module, light source module and the detector module. The optical fiber module passes light from the light source module to the sensor module. Moreover, the optical fiber module also passes reflected or transmitted light from the sensor module directly or indirectly to the detector module. The detector module detects reflected or transmitted UV light and LSPR shift from said sensor module.
