By introducing Ag NP arrays with the diameter of 40 nm Surface plasmon resonance (SPR) is used to measure binding events between molecules ranging from ions to viruses. 1 Current technology provides molecular binding with information on kinetics, affinity and very sensitive concentration measurements, with key applications in surface-enhance spectroscopy and sensing. 4 The SPR is related to the physical process that involves electromagnetic waves plasmon effect, which s a result of incident light wa transmission in periodic nanostructures [15, 16]. Although this kind of sensor has achieved high the sensitivity, its wavelength resolution remains poor because its transmission wavelength spectrum is wide [17]. However, the surface plasmon Bragg grating sensor is still based on the Kretschmann By combining surface plasmon resonance (SPR) and electrolyte gated field-effect transistor (EG-FET) methods in a single analytical device we introduce a novel tool for surface investigations, enabling simultaneous measurements of the surface mass and charge density changes in real time. This is realized using a gold sensor surface that simultaneously serves as a gate electrode of the EG-FET This effect has been the subject of extensive research, both fundamental and with a view to applications [2,3].

What is surface plasmon resonance (SPR)? Surface plasmon resonance refers to the electromagnetic response that occurs when plasmons are oscillating with the same frequency on the surface of a material. As these plasmons oscillate at specific resonant frequencies, they move with periodic driving forces that can become large amplitude oscillations when they interact. Surface plasmon resonance (SPR) is the manifestation of a resonance effect due to the interaction of conduction electrons of metal nanoparticles with incident photons. The interaction relies on the size and shape of the metal nanoparticles and on the nature and composition of the dispersion medium.
