5nm Stabilized Gold Nanoparticles

Designed for localized surface plasmon resonance (LSPR), nanoparticle conjugation, lateral flow assay development, and immunoassay development, the 5 nm stabilized gold nanoparticles format gives researchers a clear starting point when matching nanoparticle material, size and surface chemistry to an experimental workflow.

Gold nanoparticles are widely used as plasmonic labels and conjugation scaffolds because their optical response, surface chemistry and particle size can be matched to assay, imaging or sensor formats. The listed absorption maximum of 515-520 nm can help compare this size with related gold nanoparticle options.

The reactant-free format is useful when sensitive downstream workflows require minimized residual manufacturing reactants. It should be compared with standard, stabilized or endotoxin-free versions according to the application and formulation requirements of the experiment.

The supplied description emphasizes controlled size distribution and defined particle morphology. Those details matter when comparing related nanoparticle products for optical response, conjugation behavior or assay consistency.

The application profile includes localized surface plasmon resonance (LSPR), nanoparticle conjugation, lateral flow assay development, immunoassay development, and electron microscopy. These terms reflect the supported scientific workflows for this listing and help scientists compare related products by use case, not by material alone.

The small particle size is useful when compact labels, high particle number or minimal steric footprint are important selection factors.

For gold nanoparticle workflows, compare standard, stabilized, reactant-free, endotoxin-free and functionalized versions according to the application. The same size can behave differently depending on the surface chemistry and formulation.

For procurement and product selection, compare it with related nanoparticles by particle size, surface chemistry, formulation and listed application rather than treating all nanoparticles as interchangeable.
