Performance enhancement strategies for surface plasmon resonance sensors in direct glucose detection using pristine and modified UiO-66: effects of morphology, immobilization technique, and signal amplification

Au nanoparticles encapsulated in UiO-66 MOF were hybridized with Au films to generate strong coupling between their plasmon resonances. Glucose absorbing to UiO-66 modulates the local permittivity, which can be detected by the SPR sensor.
