Optical bacteriophage susceptibility testing by SPR (surface plasmon resonance) [PDF]
Plasmonics in Biology and Medicine XVIII, 2021 The proliferation of multiresistant bacteria is having an increasing and profound impact on the world. A credible alternative to antibiotics is bacteriophage therapy, which are expected in the near future to form the basis of an entirely new treatment paradigm for infectious diseases.

Surface plasmon resonance sensor based on polarization parameter SPR imaging
Optics Express, 2023 Using polarization surface plasmon resonance (SPR) imaging as a sensor has the advantage of large throughput in detection, but its sensitivity has always been inferior to other SPR sensors. The high contrast of the two polarization parameters’ images related to scattering determines the high sensitivity of this new polarization SPR imaging sensor.
