30nm Biotin Gold Nanoparticles

When streptavidin binding and assay development require a well-defined nanoparticle reagent, the 30 nm biotin-functionalized 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 526 nm can help compare this size with related gold nanoparticle options.

Biotin functionalization supports streptavidin binding and biotin-streptavidin assay design. This surface is useful when the experiment depends on modular attachment of streptavidin-labeled or streptavidin-binding components.

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 streptavidin binding and assay development. 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.
