AuNP Aptasensor for Hodgkin Lymphoma Monitoring [PDF]

Biosensors, 2022
A liquid biopsy based on circulating small extracellular vesicles (SEVs) has not yet been used in routine clinical practice due to the lack of reliable analytic technologies. Recent studies have demonstrated the great diagnostic potential of nanozyme-based systems for the detection of SEV markers.

The Role of Polymer–AuNP Interaction in the Stimuli‐Response Properties of PPA–AuNP Nanocomposites [PDF]

Macromolecular Rapid Communications, 2021
AbstractThe helical sense control of dynamic helical polymers such as poly(phenylacetylene)s (PPAs) is greatly affected when they are conjugated to AuNPs through a strong thiol‐Au connection, which restricts conformational changes at the polymer. Thus, the classical thiol‐MNP bonds must be replaced by weaker ones, such as supramolecular amide–Au ...

Lysozyme–AuNPs Interactions: Determination of Binding Free Energy [PDF]

Nanomaterials, 2021
Investigation and optimization of lysozyme (Lys) adsorption onto gold nanoparticles, AuNPs, were carried out. The purpose of this study is to determine the magnitude of the AuNPs–lysozyme interaction in aqueous media by simple spectrophotometric means, and to obtain the free energy of binding of the system for the first time.

Effect of AuNP-AuNP vdW interaction on the mechanics and piezoresistivity of AuNP-polymer nanocomposite [PDF]

AIP Advances, 2019
Gold nanoparticle (AuNP)-polymer composite has attracted considerable attention due to its high stretchability, metal-like electrical conductivity and substantial piezoresistivity. In the nanocomposite, the effect of the van der Waals (vdW) interaction increases greatly between AuNPs, which may significantly change its overall mechanical and electrical

An optically-gated AuNP–DNA protonic transistor [PDF]

Nanoscale, 2017
Bio-interface transistors, which manipulate the transportation of ions (i.e. protons), play an important role in bridging physical devices with biological functionalities, because electrical signals are carried by ions/protons in biological systems.

pH-Dependent HEWL-AuNPs Interactions: Optical Study

Molecules, 2023
Optical methods (spectroscopy, spectrofluorometry, dynamic light scattering, and refractometry) were used to study the change in the state of hen egg-white lysozyme (HEWL), protein molecules, and gold nanoparticles (AuNPs) in aqueous colloids with changes in pH, and the interaction of protein molecules with nanoparticles was also studied.

Chelating Phosphine Ligand Stabilized AuNPs in Methane Detection [PDF]

ACS Nano, 2020
The capping reagent plays an essential role in the functional properties of gold nanoparticles (AuNPs). Multiple stimuli-responsive materials are generated via diverse surface modification. The ability of the organic ligand shell on a gold surface to create a porous shell capable of binding small molecules is demonstrated as an approach to detect ...

Delivery of mixed-lineage kinase domain-like protein by vapor nanobubble photoporation induces necroptotic-like cell death in tumor cells [PDF]

, 2019
Modern molecular medicine demands techniques to efficiently deliver molecules directly into mammalian cells. As proteins are the final mediators of most cellular pathways, efficient intracellular protein delivery techniques are highly desired.
