50nm Stabilized Gold Nanoparticles

When localized surface plasmon resonance (LSPR), nanoparticle conjugation, lateral flow assay development, and immunoassay development require a well-defined nanoparticle reagent, the 50 nm stabilized gold nanoparticles format helps procurement and lab teams identify the relevant material and functional configuration.

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 536 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.

This mid-to-large nanoparticle size can be useful when stronger optical contrast or more particle surface area is desired.

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.
