31. Nano bio sensor research led to the development of the world's smallest surface plasmon resonance biochip. 32. The wavelength to which the plasmon responds is a function of the size and spacing of the particles. 33. Plasmonic waveguides, on the other hand, use surface plasmon to confine light near a metal surface. 34. Recently, cathodoluminescence performed in electron microscopes is also being used to study surface plasmon resonances in metallic Nanoparticles. 35. Recently Uchida " et al . " reported the generation of spin currents by surface plasmon resonance. 36. Surface functionalization of NMNp can be monitored in real time by UV-visible spectroscopy of the plasmon resonance. 37. The simutaneously plasmon -optical and plasmon-electrical effects of nanoparticles reveal a promising feature of nanoparticle plasmon. 38. The simutaneously plasmon-optical and plasmon -electrical effects of nanoparticles reveal a promising feature of nanoparticle plasmon. 39. The simutaneously plasmon-optical and plasmon-electrical effects of nanoparticles reveal a promising feature of nanoparticle plasmon . 40. The excitation of SPPs is frequently used in an experimental technique known as surface plasmon resonance ( SPR ).
