TLDR
In this paper, a survey is given of recent results concerning particle-size dependences of the optical plasma resonance absorption and of the FIR absorption of small noble metal particles, and it is shown that the spectra are strongly changed if the particles of a sample interact with each other.About:

Selective Colorimetric Detection of Polynucleotides Based on the Distance-Dependent Optical Properties of Gold Nanoparticles
TL;DR: A highly selective, colorimetric polynucleotide detection method based on mercaptoalkyloligonucleotide-modified gold nanoparticle probes is reported, which can detect about 10 femtomoles of an oligonucleotide.

Calculated Absorption and Scattering Properties of Gold Nanoparticles of Different Size, Shape, and Composition: Applications in Biological Imaging and Biomedicine
TL;DR: While nanorods with a higher aspect ratio along with a smaller effective radius are the best photoabsorbing nanoparticles, the highest scattering contrast for imaging applications is obtained from nanorod of high aspect ratio with a larger effective radius.

Spectral properties and relaxation dynamics of surface plasmon electronic oscillations in gold and silver nanodots and nanorods
TL;DR: In this paper, the surface plasmon absorption of noble metal nanoparticles was studied and the effects of size, shape, and composition on the plasman absorption maximum and its bandwidth were discussed.
Journal ArticleDOI
Surface Plasmon Spectroscopy of Nanosized Metal Particles
TL;DR: In this paper, the use of optical measurements to monitor electrochemical changes on the surface of nanosized metal particles is discussed within the Drude model, and the absorption spectrum of a metal sol in water is shown to be strongly affected by cathodic or anodic polarization, chemisorption, metal adatom deposition, and alloying.

Electronic Properties of Fine Metallic Particles. II. Plasma Resonance Absorption
Arisato Kawabata,Ryogo Kubo +1 more
TL;DR: In this article, the linear response theory was used to describe the quantum-mechanical treatment of fine metallic particles with a peak optical absorption around the frequency of the plasma mode and the absorption is broadened by coupling of the plasmas oscillation with the individual electronic states which are quantized in discrete levels.

Optical Properties of Small Gold Particles
TL;DR: In this paper, the optical absorption of dispersions of gold particles is studied as a function of particle size, temperature, and method of preparation, and the absorption spectra for gold sols in glass and water with small spread in particle size are compared to spectra calculated from Mie theory and the most reliable of recently measured optical constants of gold.

C. Solliard,M. Flueli +1 more
TL;DR: In this article, the authors measured the lattice contraction as a function of temperature and size of the gold and platinum rings at different temperatures and derived the surface stress coefficient and thermal expansion coefficient.

Optical Properties of Small Silver Particles
TL;DR: The optical absorption of very small silver particles in glass was measured as a function of particle size and temperature, and the shape of the measured absorption band was Lorentzian, as required by the simple freeelectron theory as discussed by the authors.
