Localized surface plasmon resonance
Localized surface plasmon resonance (LSPR) is a unique optical surface sensing technique that is responsive to refractive index changes that occur within the vicinity of a sensor surface. Thus, LSPR can be used to monitor any physical phenomenon which alters the refractive index at the surface of nanoparticles and has grown into a versatile technique used in variety of applications. Of special interest is its potential for biosensing and biomedical techniques as well as in spectral molecular resonance technique.
