Influence of gold nanoparticle surface chemistry and diameter upon Alzheimer’s disease amyloid-β protein aggregation
BACKGROUND Deposits of aggregated amyloid-β protein (Aβ) are a pathological hallmark of Alzheimer's disease (AD). Thus, one therapeutic strategy is to eliminate these deposits by halting Aβ aggregation. While a variety of possible aggregation inhibitors have been explored, only nanoparticles (NPs) exhibit promise at low substoichiometric ratios. With tunable size, shape, and surface properties,...
متن کاملOptical Properties of Gold Nanoparticle Assemblies on a Glass Surface
The assemblies of cross-linked gold nanoparticles (AuNP) attract lot of scientific attention due to feasible perspectives of their use for development of scaled contact electrodes. Here, we developed and tested method of solid-state formation of dimers created from small AuNP (~18 nm) cross-linked with 1.9-nonadithiol (NDT) molecules. The morphology of created coating of a glass surface and its...
متن کاملGold nanoparticle monolayer formation on a chemically modified glass surface.
Physicochemical analyses of Au nanoparticle monolayer formation on a glass surface functionalized with 3-aminopropyltrimethoxysilane (APTMS) and ethyltrimethoxysilane (ETMS) were performed for fabricating a nanoarchitecture of metal nanoparticles using self-assembly. The Au nanoparticle surface density on the functionalized glass surface correlated linearly with the optical response because of ...
متن کاملTunable surface-enhanced Raman scattering from large gold nanoparticle arrays.
Raman signal enhancements in excess of 10(7) can be achieved at near-infrared wavelengths when mid-nanometer sized gold particles self-organize into close-packed planar arrays. These substrates generate stable surface-enhanced Raman scattering which changes dramatically as a function of periodic structure and excitation wavelength.
متن کاملSingle-molecule gold-nanoparticle tracking.
Gold nanoparticles, like single fluorophores, can be used to locate single molecules with nanometer accuracy. Unlike an optical trap, the gold particle label does not exert an external load, which is important for studying diffusive processes. Thus, a gold particle can be used analogously to a single fluorophore, providing similar information but with submillisecond time resolution. The feature...
