5nm Amine (amine-PEG3000-SH) Gold Nanoparticles

Designed for nanoparticle conjugation and protein labeling, the 5 nm amine-PEG 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 amine-functionalized surface provides a reactive handle for ligand coupling and protein-labeling workflows. It is useful when the experimental design requires a nanoparticle with amine surface chemistry rather than a passive-adsorption format.

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 nanoparticle conjugation and protein labeling. 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.

Application areas

• Nanoparticle conjugation with supported proteins, ligands or biomolecules
