Synthesis of Gold Nanorods for Multifaceted Applications

ECSOC 2023, 2023
Different length gold nanorods (AuNRs) were synthesized using different methods. The obtained AuNRs were characterized using scanning electron microscopy (SEM), dynamic light scattering (DLS) technique, and UV-Vis spectroscopy. These techniques allowed for a detailed study of the structural and optical properties of the AuNRs and provided valuable ...

Hydroquinone Based Synthesis of Gold Nanorods [PDF]

Journal of Visualized Experiments, 2016
Gold nanorods are an important kind of nanoparticles characterized by peculiar plasmonic properties. Despite their widespread use in nanotechnology, the synthetic methods for the preparation of gold nanorods are still not fully optimized. In this paper we describe a new, highly efficient, two-step protocol based on the use of hydroquinone as a mild ...

Blood–Brain Barrier Regulation: Evolving From Classic Strategies to Electrochemical Ion and Reactive Oxygen Species Control

Advanced Healthcare Materials, EarlyView.
Conventional therapies suffer from poor blood–brain barrier (BBB) penetration and disordered ion/reactive oxygen species (ROS) homeostasis, hindering precise neurological treatment. Electrochemical strategies achieve accurate spatiotemporal regulation of neural homeostasis.

Gold-Nanorod-Based Plasmonic Nose for Analysis of Chemical Mixtures

, 2019
We introduce the “plasmonic nose” as a novel approach for detection, recognition, and quantification of mixtures of chemical species. Using a paper substrate and a calligraphy-based fabrication approach, we generated an array of surface-enhanced Raman ...

Uptake and cytotoxicity of citrate-coated gold nanospheres : comparative studies on human endothelial and epithelial cells [PDF]

, 2012
The use of gold nanoparticles (AuNPs) for diagnostic applications and for drug and gene-delivery is currently under intensive investigation. For such applications, biocompatibility and the absence of cytotoxicity of AuNPs is essential. Although generally

Near‐Infrared Light‐Activated Polydopamine Nanoparticles Conjugated With Transferrin Peptides for Enhanced Brain Accumulation

Advanced Healthcare Materials, EarlyView.
This study demonstrates that Tf‐PDA NPs combine a receptor‐mediated targeting with mild photothermal activation to enhance nanoparticle accumulation in the brain. NIR‐activated Tf‐PDA NPs increase BBB permeability to NPs in vitro and in vivo without inducing cytotoxicity or adverse immune responses.

CONFORMATIONAL STRUCTURE OF POLYAMPHOLYTES AND POLYELECTROLYTES ON THE SURFACE OF A LONGITUDINALLY POLARIZED GOLD SPHEROCYLINDER

Eurasian Physical Technical Journal
Conformational changes in generally neutral polyampholytic, as well as uniformly charged macrochains, polypeptides adsorbed on the surface of a longitudinally polarized gold spherocylinder—a cylindrical nanorod with spherical ends—were studied.
