We study the surface plasmon (SP) resonance energy of isolated spherical Ag nanoparticles dispersed on a silicon nitride substrate in the diameter range 3.5–26 nm with monochromated electron energy-loss spectroscopy. A significant blueshift of the SP resonance energy of 0.5 eV is measured when the particle size decreases from 26 down to 3.5 nm. We interpret the observed blueshift using three

The LSPR related absorbance intensity and wavelength were shown to be dependent on shape and size of the nanoparticles, and can be further controlled by varying the stoichiometric ratio and aspect ratio of the nanoparticles [37] , [38] . Signal enhancement by gold nanoparticles is caused by several effects such as surface mass increase due to enhanced surface area, larger refractive index changes by the particle mass, themselves, and electromagnetic field coupling between the plasmonic properties of the particles (localized surface plasmon resonance) and propagating plasmons.

This is a lecture from the Nanomanufacturing course at the University of Michigan, taught by Prof. John Hart. For more information, see http://www.mechanosyn Localized surface plasmon resonance is generated by metal nanoparticles, typically gold and silver, as compared to a continuous film of gold as used in traditional SPR. LSPR produces a strong resonance absorbance peak in the visible range of light, with its position being highly sensitive to the local refractive index surrounding the particle.

Plasmonics & Surface Plasmon Resonance. The unique optical properties of plasmonic nanoparticles have been observed for thousands of years. Since ancient times artists have used colloidal nanoparticles of gold, silver, and copper to give color to pottery and stained glass. Surface Plasmon Resonance and Nanoparticles . Nanoparticles are of interest to the scientific community for a multitude of reasons including their large surface area to volume ratio which makes them very reactive to external stimuli quickly, the fact that they operate on a quantum mechanics scale, and because the nanoscale is the level at which many biological processes occur.
