400nm Stabilized Gold Nanoparticles

For laboratories developing localized surface plasmon resonance (LSPR), nanoparticle conjugation, lateral flow assay development, and immunoassay development, the 400 nm stabilized gold nanoparticles format provides a defined material option for online scientific purchasing and product selection.

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 stabilized format is intended for workflows where colloidal behavior and handling robustness are important selection factors. For gold nanoparticle conjugation, the surface is suitable for passive adsorption strategies described in the product data.

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 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 larger particle size is useful when the workflow benefits from increased scattering, visible signal or particle-size discrimination.

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.
