New Spectroscopy Study Results from Xidian University Described (Optimal dimensions of gold nanoshells for light backscattering and absorption based applications)

By a News Reporter-Staff News Editor at Science Letter -- Research findings on Spectroscopy are discussed in a new report. According to news reporting originating in Xi'an, People's Republic of China, by NewsRx journalists, research stated, "Gold nanoshells, a novel type of composite spherical nanoparticle consisting of a spherical dielectric core covered by an ultrathin gold shell, have been used as contrast agents for biological imaging as well as therapeutic agents for photothermal therapy based on their strong backscattering and absorption properties. In this paper, we investigate the dependence of the backscattering and absorption properties of silica core-gold nanoshells on the core radius and shell thickness by using the Mie theory for a coated sphere with the size-dependent dielectric function of metal nanoparticles."

The news reporters obtained a quote from the research from Xidian University, "Our results show that, by varying the core radius and shell thickness, the position and intensity of the backscattering and absorption resonance peak can be tuned within the visible and near-infrared regions. We obtain the optimal dimensions of silica core-gold nanoshells for light backscattering and absorption based applications: biological imaging, photothermal therapy, and combined biological imaging and photothermal therapy."

According to the news reporters, the research concluded: "The optimized gold nanoshells can be used as ideal contrast and therapeutic agents."
