90nm Methylated (methoxy-PEG2000-SH) Gold Nanoparticles

In workflows involving assay development and non-specific binding control, the 90 nm methoxy-PEG gold nanoparticles format is positioned as a defined nanoparticle configuration rather than a generic listing.

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 564 nm can help compare this size with related gold nanoparticle options.

The methoxy-PEG surface is intended for workflows where reduced non-specific protein binding is important. It is particularly useful as a control particle or as a comparison point against reactive or protein-binding nanoparticle surfaces.

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 assay development and non-specific binding control. 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.

Application areas

• Assay development and comparison of nanoparticle size or surface chemistry
• Control experiments focused on low or reduced non-specific binding
