Gold Nanoparticles as Absolute Nanothermometers [PDF]

Nano Letters, 2018
Nanothermometry is a challenging field that can open the door to intriguing questions ranging from biology and medicine to material sciences. Gold nanorods are excellent candidates to act as nanoprobes because they are reasonably bright emitters upon excitation with a monochromatic source. Gold nanoparticles are commonly used in photothermal therapy as

Synthesis of Gold Nanoparticles and Association of DNA-Gold Nanoparticles

Eurasian Chemico-Technological Journal, 2009
This study examined the synthesis of gold nanoparticles using a non-ionic surfactant, polysorbate 80, and KAuCl4 in water. The gold nanoparticles, which were well dispersed in water, were analyzed by UV-vis spectroscopy and transmission electron microscopy (TEM).

Interaction of gold nanoparticles with mitochondria

Colloids and Surfaces B: Biointerfaces, 2009
Mitochondrion is one of the most important organelles in cells with several vital responsibilities. The consequence of a deficiency in the function of mitochondrion could result with the wide range of diseases and disorders. In this study, we investigated the feasibility of utilizing surface-enhanced Raman scattering (SERS) to understand the mode of ...

Differential Uptake of Gold Nanoparticles by 2 Species of Tadpole, the Wood Frog (Lithobates Sylvaticus) and the Bullfrog (Lithobates Catesbeianus)

, 2017
Engineered nanoparticles are aquatic contaminants of emerging concern that exert ecotoxicological effects on a wide variety of organisms. We exposed cetyltrimethylammonium bromide–capped spherical gold nanoparticles to wood frog and bullfrog tadpoles ...

Broadband enhancement of the magneto-optical activity of hybrid Au loaded Bi:YIG [PDF]

, 2019
We unravel the underlying near-field mechanism of the enhancement of the magneto-optical activity of bismuth-substituted yttrium iron garnet films (Bi:YIG) loaded with gold nanoparticles. The experimental results show that the embedded gold nanoparticles
