Optimized gold nanoshell ensembles for biomedical applications

Optimized gold nanoshell ensembles for biomedical applications

: We theoretically study the properties of the optimal size distribution in the ensemble of hollow gold nanoshells (HGNs) that exhibits the best performance at in vivo biomedical applications. For the first time, to the best of our knowledge, we analyze the dependence of the optimal geometric means of the nanoshells' thicknesses and core radii on the excitation wavelength and the type of human ...

Gold Nanoshells in Biomedical Applications

Biomedical Applications of Gold Nanoparticles

Gold nanoparticles display unique properties which allow them to influence a number of different biochemical processes. Interestingly, these effects are dependent on the particle surface chemistry which varies considerably based on the particle size. In addition, unlike most of other nanomaterials, gold nanoparticles do not trigger the formation of pro-inflammatory multiprotein complexes, known...

Gold-gold sulfide nanoshell as a novel intensifier for anti-tumor effects of radiofrequency fields

Objective(s):Several studies have been carried out to investigate the effect of various nanoparticles exposed to radiofrequency (RF) waves on cancerous tissues. In this study, a colon carcinoma tumor model was irradiated by RF in the presence of gold-gold sulfide (GGS) nanoshells. Materials and Methods: Synthesis and characterization of GGS nanoshells were initially performed. CT26 cells were ...

Functionalized Gold Nanoparticles and Their Biomedical Applications

Metal nanoparticles are being extensively used in various biomedical applications due to their small size to volume ratio and extensive thermal stability. Gold nanoparticles (GNPs) are an obvious choice due to their amenability of synthesis and functionalization, less toxicity and ease of detection. The present review focuses on various methods of functionalization of GNPs and their application...
