Encapsulation of Gold Nanostructures and Oil-in-Water Nanocarriers in Microgels with Biomedical Potential
(2018)
Here we report the incorporation of gold nanostructures (nanospheres or nanorods, functionalized with carboxylate-end PEG) and curcumin oil-in-water (O/W) nanoemulsions (CurNem) into alginate microgels using the dripping ...
High performance gold nanorods and silver nanocubes in surface-enhanced Raman spectroscopy of pesticides
(ROYAL SOC CHEMISTRY, 2009)
The behavior of Au nanorods and Ag nanocubes as analytical sensors was evaluated for three different classes of herbicides. The use of such anisotropic nanoparticles in surface-enhanced Raman scattering (SERS) experiments ...
Exploring the influence of diels–alder linker length on photothermal molecule release from gold nanorods
(Elsevier, 2018-06)
We studied the photothermal release of carboxyfluorescein (CF) linked to the gold surface of gold nanorods (GNRs) by two Diels-Alder adducts of different lengths (n = 4 and n = 9). The functionalized GNRs were irradiated ...
Monitoring the photothermal reshaping of individual plasmonic nanorods with coherent mechanical oscillations
(American Chemical Society, 2018-12-03)
Light absorption in gold nanoparticles leads to metal heating that induces photothermal reshaping because of atomic surface diffusion at temperatures well below the gold melting point. In this work, we perform time-resolved ...
In situ imaging of gold nanocrystals during the CO oxidation reaction studied by Bragg Coherent Diffraction Imaging
(Universidade Estadual Paulista (Unesp), 2019-03-26)
O principal objetivo da catálise heterogênea é entender os mecanismos de reação a nível nanométrico e planejar/sintetizar catalisadores com os sítios ativos desejados. A este respeito, a caracterização de defeitos in ...
Synthesis and characterization of extremely small gold nanoshells, and comparison of their photothermal conversion capacity with gold nanorods
(Royal Society of Chemistry, 2016-04-20)
The current methods for preparing gold nanoshells (AuNSs) produce shells with a diameter of approximately 40 nm or larger, with a relatively large polydispersity. However, AuNSs with smaller diameters and more monodispersity ...
Changes in antiparasitical activity of gold nanorods according to the chosen synthesis
