Journal ArticleDOI
Chemistry and properties of nanocrystals of different shapes.
TL;DR: The interest in nanoscale materials stems from the fact that new properties are acquired at this length scale and, equally important, that these properties are equally important.
Journal ArticleDOI
Cancer Cell Imaging and Photothermal Therapy in the Near-Infrared Region by Using Gold Nanorods
TL;DR: It is found that, after exposure to continuous red laser at 800 nm, malignant cells require about half the laser energy to be photothermally destroyed than the nonmalignant cells, so both efficient cancer cell diagnostics and selective photothermal therapy are realized at the same time.
Journal ArticleDOI
Preparation and Growth Mechanism of Gold Nanorods (NRs) Using Seed-Mediated Growth Method
TL;DR: In this article, a method was used for preparing gold NRs with aspect ratios ranging from 1.5 to 4.5 for which the surface plasmon absorption maxima are between 600 and 1300 nm.
Journal ArticleDOI
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.
Journal ArticleDOI
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.
