13nm Reactant Free Gold Nanoparticles

When surface-enhanced Raman spectroscopy (SERS), nanoparticle conjugation, lateral flow assay development, and immunoassay development require a well-defined nanoparticle reagent, the 13 nm reactant-free 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 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 notes controlled particle sizing and dynamic light scattering assessment of size and monodispersity. That context is useful for assays where optical response, conjugate behavior or particle-size comparisons need to be reproducible.

The application profile includes surface-enhanced Raman spectroscopy (SERS), nanoparticle conjugation, lateral flow assay development, immunoassay development, electron microscopy, and toxicity studies. These terms reflect the supported scientific workflows for this listing and help scientists compare related products by use case, not by material alone.

This size range is often selected as a balance between particle number, optical response and biomolecular surface area.

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.
