Novel bioactive glass-AuNP composites for biomedical applications

Materials Science and Engineering: C, 2017
The bioactive glasses doped with gold nanoparticles (AuNPs) are very attractive materials due to their potential in medical applications. In the present study Pluronic-nanogold hybrid nanoparticles were introduced during the sol-gel route of the SiO2-CaO-P2O5 glasses preparation.

Multilayer Model of Gold Nanoparticles (AuNPs) and Its Application in the Classical Molecular Dynamics Simulation of Citrate-Capped AuNPs

The Journal of Physical Chemistry B, 2023
Studies on the interaction between gold nanoparticles (AuNPs) and functional proteins have been useful in developing diagnostic and therapeutic agents. Such studies require a realistic computational model of AuNPs for successful molecular design works. This study offers a new multilayer model of AuNPs to address the inconsistency between its molecular ...

DNA/AuNP Fluorescent Detecting Nano-Device

Advanced Materials Research, 2012
A DNA/AuNP (gold nanoparticle) detecting nano-device has been constructed using DNA displacement (three-way branch migration).Here, DNA/AuNP conjugations and DNA circle are utilized as basic parts in nano-system, while sensitive fluorescent signals are applied as output results.

A facile synthetic approach and optical properties of AuNPs/CdSe tetrapod and AuNPs/CdSe@rGO nanocomposites

Journal of Molecular Liquids, 2019
Abstract New heterostructures (tetrapods-like shape) were synthesized using AuNPs/CdSe hybrid nanocomposites in a facile synthetic route. The growth mechanism of such heterostructures was based on “Direct Heterogeneous Deposition” mechanism, in which the heterogeneous nucleation growth of CdSe arms (nanorods) structured at the nucleating sites on the

Graphene/AuNPs/chitosan nanocomposites film for glucose biosensing

Biosensors and Bioelectronics, 2010
A novel glucose biosensor based on immobilization of glucose oxidase in thin films of chitosan containing nanocomposites of graphene and gold nanoparticles (AuNPs) at a gold electrode was developed. The resulting graphene/AuNPs/chitosan composites film exhibited good electrocatalytical activity toward H(2)O(2) and O(2).

Fluorogenic Gold Nanoparticle (AuNP) Substrate: A Model for the Controlled Release of Molecules from AuNP Nanocarriers via Interfacial Staudinger–Bertozzi Ligation

Langmuir, 2017
The ability to regulate small-molecule release from metallic nanoparticle substrates offers unprecedented opportunities for nanocarrier-based imaging, sensing, and drug-delivery applications. Herein we report a novel and highly specific release methodology off gold nanoparticle (AuNP) surfaces based on the bioorthogonal Staudinger-Bertozzi ligation.

Self‐Crosslinking AuNPs Composite Hydrogel Bolus for Radiophotothermal Therapy

Macromolecular Rapid Communications
AbstractRadiophotothermal therapy is a promising treatment for superficial tumors. Traditional radiotherapy requires tissue boluses on the patient's skin to increase therapeutic effectiveness due to the dose‐buildup effect of high‐energy radiation. However, combining radiotherapy with photothermal therapy leads to uncertainties as the low‐penetration ...
